Adult Crystal Mermaid Tail 

Swim deep and far into the ocean and find Atlantis sunken deep below, this shiny blue mermaid tail has a stiff dense foam build to give it a semi permanent form of your choosing and an easy latch on attachment for all night hold. Great costume ideas would be Ariel, Poseidon, Aquamarine, or to be even more creative, a Siren like in the movie Harry Potter and the Goblet of Fire. Can be worn by both adults and children.
