This is a diagonally-worn knapsack knitted from 100% cotton! Because it's knitted from cotton, it's less likely to stretch than usual, which is recommended. ⚠︎We recommend that you put a drawstring bag inside. The length of the string can be adjusted by retying it! Although it is made with care, it is handmade by an amateur, so please refrain from purchasing if you are sensitive or looking for a perfect product. The image is the third photo!
