For those who like it, please consider purchasing. It's 33x27cm with a base of 8cm. The shoulder strap is 138cm long, so it can be shortened, and it can also be worn diagonally. It has cushioning, so it's safe to put in a tablet, etc. There's one zippered opening and one large opening inside the outer flap. There is a signature on the back of the outer flap because it's an original from a conference. If you don't mind, please consider purchasing. #Usamaru's bags are also available GW2F9
