This is a prize I won from a Sanrio Ichiban Kuji lottery. It's a mini tote bag featuring Hello Kitty, My Melody, and Kuromi. Although it's mini, the height is about the size of my hand, and the width is about the size of two hands. It might be just the right size for a lunch bag! The material is listed as polyester. It's new and unopened, but please understand that it has been stored at home. Thank you for looking.
