it is customize item.so usually it will not accept cancel after make order,

and also can not accept return if the tail is no problems, hope understand!!! tks!

PS:The tail is made of spandex, not silicone, hope could understand!

and the tail is too big,so, if you have your own monofin, can put it in.

we also have big monofin in store, can contact us for details.
