There's no lovely greeting card in the metallic-decorated envelope - it's a gag from the kitchen:a sponge that pops up surprisingly thick when you hold it under water for the first time.
This sponge is fun for everyone and makes a great gift! It has a roughly round shape, although the exact shape of each pop-up sponge is a secret until it gets wet.This is in its nature, the sponge is made from 100% sustainable cellulose.
