    "... The design is amazing and in the water the skin looks so real! I was wary of this tail at first because the "fluke" monofin looked too small for my preference.let me just say that this tail swims perfectly! It is the perfect size! So in love with their monofin design very comfortable! I underestimated this tail!"

    "Amazing!!! I purchased this mermaid tail for my 7 year old daughter for Christmas. She loves it! It is extremely durable and makes you look like a real mermaid. very flexible. simple to put on and remove. comfortable and easy to move around in. Great buy! Do not go cheap and buy an off brand knock off. Put up the money and get the real deal. Best mermaid tail ever!"

how fin fun mermaid tails started

It all started with a little girl's dream to be a mermaid

In 2009, when Emily was about 11 years old, she dreamed of swimming like a mermaid. Desperate to fulfil her dream, she begged her Grandma to make her a real mermaid tail that she could swim in. Well, "Grandma Karen" went to work designing, sewing, fitting and finally created a beautiful mermaid tail that Emily could really swim in! Soon Emily's cousins wanted their own mermaid tails. Then their friends... and their friends. Soon Grandma Karen was selling her creations online and Fin Fun Mermaid Tails was born. And Grandma Karen was sewing just as fast as she could to keep up with demand.

Fast forward to today. Fin Fun Mermaid is still making mermaid tails and selling them all over the world! Grandma Karen doesn't sew them anymore, but she still owns the company and many of her children and grandchildren are running the business. You'll see some of them in the popular YouTube series, Fin Fun World News.

    "First, I want to thank you. My daughter discovered... fin funs earlier this summer. I was really dubious because although she LOVED the idea, in reality she had issues in the water...But fin fun just changed everything. She knew! She loved her tail and took to the water like a mermaid in it from day 1. We have been at a pool and more recently a local lake almost everyday since it arrived in August. She is now an excellent swimmer! Oh, and lastly she and her friends are making a mermaid series of their own now, and in the process my daughter has taught herself so much about iMovie. She's 11. Oh, and also, I got a tail myself and love it too!" ~October 20, 2014
