Safety Warning

Adult supervision and a monofin are always required for this product. Swimming in any tail without a monofin, or without adult supervision, could lead to injury or death. Children should never be left unsupervised in or near water. Click here to purchase a children's monofin if you do not already own one!

What is a Monofin?

If you want your beautiful mermaid tail to keep its shape in the water, and so you can swim in it, you will need to purchase a monofin. A monofin provides propulsion - you will not be able to swim properly without it.

Swimming without a monofin will create loose pockets of fabric around
the feet that will prevent proper swimming, and cause safety issues.

Important Info

Mermaid tail sets are manufactured by a third party, and inspected for
quality control by Lemonade Mermaid. Please allow at least 4-6 weeks for production and delivery.
