The metallic-decorated envelope doesn't contain a sweet greeting card – it's a kitchen gag: a sponge that pops up surprisingly large 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 remains a secret until it gets wet. This is due to its nature; the sponge is made from 100% sustainable cellulose.
