Size: Approximately 45cm. This 2-way item can be used as a placemat when unfolded, and as a drawstring bag when the strings are pulled. It's also convenient for wrapping lunches, storing small items, or as a travel pouch. I opened it once, but I'm selling it because I never had the chance to use it. The item itself has never been used and is in like-new condition. Please refrain from purchasing if you are concerned about it being stored at home.
