This is a lunch tote bag featuring illustrations of 8 characters: Rin Itoshi, Sae Itoshi, Reo, Nagi, Kunigami, Chigiri, Bachira, and Isagi. It does not have a cooling effect. This item was sold at the Blue Lock Tree Village Cafe. I purchased it and opened it once, but I ended up not using it, so I am offering it for sale. The official size is approximately W280 x H180 x D90mm.
