Used when my child was in kindergarten. The frequency of use was only once a month for bento box days and field trips over the course of three years. There are some scratches on the surface, but it's in relatively good condition. There are scuffs and discoloration on the four corners of the inside. Please check the images and only purchase if you are not concerned. Also, the lunch belt is not included because it has stretched out. Please be aware of this.
