Our Mermaidens tails are designed with a mermaid pattern printed directly on the fabric. They are durable, realistic, and absolutely beautiful! They are also machine washable. They featured reinforced tips to protect against wear and tear.

Our Limited Edition Mermaid Tails are similar to Mermaidens tails, except that they feature unique shiny textures over the entire tail fabric, which gives them extra shimmer and a special sleek feeling in the water, just like a REAL mermaid! They also feature reinforced tips to prevent wear and tear.

Our Atlantis Mermaid Tails are more elaborate tails that feature added fin extensions on the sides, back and ankle areas. The tails are made from the same swimsuit fabric with printed design, and the fins have a neoprene foam filling to create a realistic 3D effect in the water. Atlantis Tails also feature reinforced tips.

Our Sparkle Mermaid Tails are shiny and beautiful! However, their sparkly nature makes them prone to faster wear. Sparkle Tails are perfect as costume tails or for playing in the bathtub, but not intended for swimming in chlorine or salt water. These tails do not have reinforced tips and are not machine washable.

All Mermaid Tails sold on are proudly designed in Idaho Falls, ID. We work with a network of international manufacturers, each of whom must meet our strict quality standards.

At Fin Fun, we are very passionate about creating the safest products possible. As a general rule, we recommend children wait until they are at least 6 years old AND a strong swimmer to swim in one of our mermaid tails. However, no matter the age or skill, adult supervision is a must!

For the littlest mermaids, our Toddler Tails in sizes 3T and 5T make the perfect dress-up tail. These tails can be worn in water and are designed for use without the monofin. The bottom is flared like a mermaid skirt to allow for free leg movement in water and easy walking on land.

Like any specialty fabric, Fin Fun Mermaid Tails need special care to prevent damage and fading. To prevent wear and preserve the beauty of your new mermaid tail, always use a genuine Fin Fun monofin with your tail. Also, avoid rubbing your tail against rough surfaces like the bottom of a pool or standing in your tail (tail should be pulled up above the ankles when not in the water). Our suits and mermaid tails are breathable and made from the same material as a normal swimsuit for maximum comfort, so pilling or slight fading from rubbing against rough surfaces can occur.

Fin Fun tails now feature innovative patented tip reinforcement technology, and we stand behind the premium quality of our reinforced tail tips with the best purchase protection guarantee in the industry. See below for details on our 1-Year Tail Tip Warranty available on all Mermaidens and Limited Edition swimmable mermaid tails.*

Mermaidens Mermaid Tails, Limited Edition Mermaid Tails, & Coordinating Swimsuits:

These can be machine washed in a gentle cycle with cool water. After washing, hang and allow to drip-dry.

Atlantis Mermaid Tails:

Because of the added fins, Atlantis tails should only be hand washed and hung to air dry. Do not wring or twist, and do not dry clean. Do not use bleach or iron as it may damage the tail design.

Sparkle Costume Tails & Matching Sparkle Swimsuits:

Turn your tail inside out and gently hand wash using a mild detergent. Instead of squeezing or rubbing, gently swish the garment through the water. Focus on actual stain spots rather than attempting to wring or rub the entire garment. After rinsing, DO NOT wring out the garment as it can damage the glitter and the spandex fibers. Rinse the garment in cool water and lay flat on a towel. Carefully roll up the towel, squeezing out excess water. Hang and allow to drip-dry.

*Use of a monofin other than Fin Fun brand voids this warranty. Does not include Toddler Tails.

Why are Fin Fun’s tails open at the bottom?

We have designed our mermaid tails to be open at the bottom to make it easy to put on and pull off the monofin inside the mermaid tail. This helps keep your mermaid safe while swimming, as the monofin can be easily removed. The separate monofin also allows you to add new mermaid tail skins to your mermaid wardrobe without purchasing an additional monofin each time. We have found that a mermaid tail open at the bottom is the best choice for safety and maximum flexibility.

Orders will not be processed or shipped on holidays. After the order has been shipped, you will receive a confirmation email with shipping/tracking information.

We are not responsible for delays caused by factors beyond our control, such as weather, transportation strikes or natural disasters.

If you are ordering internationally, please track your package closely to make sure that it is delivered in a timely manner. We have found that our international customers receive their package more quickly when this is done. In the past, some postal services have held onto packages without notifying customers for several days. If your order is late, check with the shipping company or your local postal service before contacting us.

What should I do if I haven’t received an order confirmation email?

The order confirmation email should arrive shortly after the order is placed. If you can’t find the confirmation, please check your SPAM or JUNK folders. If you still can’t find the confirmation, please contact our Customer Service team at to confirm that the order has been processed.

What should I do if I haven’t received a shipping confirmation email?

If it has been more than 2 business days since you placed your order and received an order confirmation email, but you still have not received a shipping confirmation email, we recommend you first check your SPAM or JUNK folder to make sure it is not there. If you cannot find it, you may contact Customer Service at or 1-844-4FINFUN ( 844-434-6386) and press option 1 for customer service. On rare occasions, it may take up to 2 business days for a product to ship if there are unforeseen circumstances such as inclement weather, technical issues, or other unusual occurrence.

If you never received your order confirmation email, you should also check your SPAM or JUNK folder for these emails. If you cannot find either email, it is likely that your order did not go through and you should contact Fin Fun Customer Service immediately at or 1-844-4FINFUN ( 844-434-6386).

I received a shipping confirmation email, but I didn’t get a tracking number. Is something wrong?

All shipping confirmation emails should include a tracking number. Please contact our Customer Service team at if you did not receive a tracking number.

Are there other shipping or handling charges that I might expect for International orders?

Some countries charge import or custom fees or other third party handling fees. Fin Fun has no control over the imposition of these fees and the customer will be required to pay these fees before the package can be delivered. If you have questions or concerns about these fees, please contact your import authorities. These fees, especially in Greece, Spain, Canada, Brazil, and the UK, can be significant and delivery may be delayed until the fees are paid.

In the past, some postal services have held onto packages without notifying customers for several days. If your order is late, check with the shipping company or your local postal service before contacting us.

Australia and some other countries do not charge duties or fees on orders less than $1,000. Be sure to check with your country to determine what fees you must pay to receive your package.

Payment Questions

What payment types do you accept? Is your site secure?

We accept payment through Visa, MasterCard, American Express and Discover. We also accept all major credit cards that are processed through PayPal, as well as PayPal quick checkout options that allow you to use funds directly from your PayPal account.

Regardless of your preferred method of payment, your information is secure and protected. We use EV SSL payment security by GoDaddy to provide you with the highest level of confidence during check out. When you see the top navigation bar change to "https:" as part of the checkout process, you will know your information is secure. We do not retain your credit information.

We use credit card tokenization that allows you convenient access to your credit card without storing the actual card information with Fin Fun. Instead, it is secured by a leading payment processing provider using the highest level of security to protect your payment information.

All prices are in US dollars.

My order won’t go through. Why not?

Often an order fails to go through due to incorrect or incomplete credit card information. The most common problems are using a billing address that does not match the card used or forgetting to include the CVV number. The CVV number is the 3-digit security code usually found on the back of the credit card. Occasionally a credit card will be declined for various other reasons. Orders cannot be processed until payment is accepted.

If the credit card payment is accepted, but the order won't go through, it may be a technical problem with the website. Please send an email to or call us at 1-844-4FINFUN and press option 1 for customer service.
