This is an official Lee Min-ho A3 size goods lunch mat. It's a product that immediately sold out at a fan meeting in Seoul. I have never taken it out of the bag, but the opening was not originally sealed with tape as shown in the third photo, so it is not completely unopened. I think the material is the same as a mousepad? Please understand this is based on my personal observation. Shipping will be via Yu-Packet Post in a dedicated box, folded in half (I will put air cushioning in the middle to prevent it from being completely crushed). Please understand that this is for long-term storage.
