    Longer Review and more pics on google. Emerald/Mint Genesis Edition

    ABSOLUTLY fantastic company to work with! Erin Gallagher, Owner/Artist is amazing sent me constant updates, pictures, east to follow tail videos, and went above and beyond in every way to make my experience completely magic. I was expecting the tail in 3-4 months like advertised, I was emailed 2 weeks (A Monday) after ordering and sending my duct tape dummy that they would be able to get my tail done that week which lead to every other day picture updates, and it being sent out that Thursday and receiving the package in a week!

    The tail is absolutely stunning with a faint glitter shine on it that makes my feel like a princess. It has gorgeous colors that are super rich and dreamy. I 100% recommend this company to anyone considering a silicone mermaid tail!

    Don't even know where to begin with how amazing our experience with MerNation was! Erin spent half an hour on the phone with me before even placing our order to talk through specifics on how everything works, and has been so helpful and attentive throughout the entire process! She and her team did an AMAZING job with our tails- the quality is just as it's shown in the picture and the tails swim flawlessly in the water! MerNation kept us updated with pictures of our tails as they were being made and let us know as soon as they were placed in the mail. We've already had 2 great experiences with using MerNation and hope to continue to use them for even more tails as we move forward! The quality of both the customer service and the products themselves far exceed expectations and you won't be disappointed!

    MerNation is a dream to work with! Their products are of excellent quality and their customer service is unmatched. I also ordered a matching silicone tail from them after my previous tail company screwed me over with my order. MerNation to the rescue! They had my dream tail designed and in my hands in 4 weeks!! (I paid a rush fee, but still!) Don't let the other companies tell you it takes 1.5 years to get a quality tail. Thank you, MerNation!

    So the tail was more than what I expected, the top as well. It was to say the least beautiful. The creator will help you every step of the way to create one of the most beautiful creations ever that you could possibly dream up. There was constant video footage of the creation process as well as pictures. This company have amazing artist who take there time with creation. The best part is the small openings at the end of the fluke to flick out the gathered water after swimming. The top I ordered also have removable straps and was adjusted just enough so that my stomach shows with the tail. The gold blends in well with my skin tone. Thanks Mernation!

    It is absolutely beautiful, and everything I asked for! The quality is great and I can't wait to swim in it. Plus it shipped right on time. Thank you MerNation!

    I love my tail! It came in really quickly and was packaged safely. I took it for its first swim this morning and loved it! The way they made the monofin was so comfortable on my feet. It didn't rub or anything, I forgot it was there. However, if you don't want glitter all over your hands, house, and pool, get the glitter-less version (I wanted glitter all over my hands, house, and pool so it worked out perfectly ;D) The material was thick and strong and the way they made the elastic strap around the waist kept it from falling down, but didn't cut into my belly (which I was concerned about). Lauren was very helpful emailing back and forth with me. Five stars, Mernation!

    Love this company!!! Customer service is fabulous and all their products are fabulous. I also have one of their silicone tails and it's beautiful! I love the gap wrap it's perfect to give that extra something and to keep unwanted things out of view. ;)

    This item is spectacular! It's beautiful, it fits perfectly to my specified measurements, and it's so much fun to swim in. The spandex quality really is worth the price. Other spandex tails can't really stand up to this. The fabric is thicker than standard swimsuit spandex and more comfortable. It also came extremely fast. The day after I got my invoice for shipping, the tail arrived. And it was still 2 weeks sooner than expected! I love this company and this tail. If I can ever afford a silicone one, I'll be making a purchase with MerNation!

Make Your Mermaid Dreams a Reality!

We could say that the story of MerNation started many years ago as one of our founders would play "mermaids" in the pool with her friends. Every day they would dream of becoming one of these beautiful mythical creatures and make "tails" to swim with.

As these girls grew older, they realized that playing mermaids is something that everyone can relate to, as both children and adults. It's about transforming into something magical, and living out a dream underwater. Now working hand in hand with a fellow artist and professional diver, they create functional mermaid costumes that are both beautiful and durable.

MerNation, Inc. was formed to give people the opportunity to embrace these fantasies, and sometime turn them into a lucrative career! By purchasing one of our handmade, custom fit and designed products you can be one step closer to being a real life mermaid. Whether your dream is to begin your own business as a professional mermaid, or just live your fantasy of swimming like a mermaid, we can bring that dream to life.

Let us take your fantasies and designs and turn them into reality!
