Used once, then washed and disinfected. The blade isn't sharp enough to cut your hand, so it's safe for children to handle. It's not just for pizza; it can also be used for cutting bread, pie crusts, and more. Depending on how you look at it, it seems to have a wide range of uses, such as for crafts and DIY projects. It's a little difficult to wash, but because it's transparent, you can see the dirt, so you don't have to worry about missing any spots. It's compact and easy to store. Will be shipped via Yu-Packet.
