Everything you want to know
We have already collected the most important questions and answers for you😊
What is included
Good to know: the loose mermaid tail does not include a monofin.
Extra strong fabric
When choosing the fabric, we took into account two important properties, weight and quality. We tested various fabrics on this and eventually found a perfect combination for the new collection.
A sturdy fabric that can withstand a beating so that the mermaids can enjoy it for as long as possible. But super light so that they can swim easier and lighter.
Improved protection of the tail tips
Just like last year, the new collection also has extra reinforcement on the points of the tail, because this is the most vulnerable part. This year, a different method of application has been chosen, which means that this reinforcement will stay in place even better and longer.
Now with a 12-month warranty
New this year is also the extra extended warranty . We are so convinced of the quality that we can increase the warranty on the new collection to 12 months !
Swimming diploma
We recommend diploma A and B for the use of the mermaid tail and ensure that swimming is always supervised.
