I liked this and used it often for a while. I think the small compartments on the outside and the dividers inside were easy to use. I think it's probably cotton. The adhesive of the interfacing at the seams seems to have caused some discoloration. It's not dirty from the outside, but the color is coming out from between the weave. It's quite worn, but it still seems usable as a bag-in-bag, so I'm listing it. If you like the worn look, please consider purchasing. My use of it decreased after I switched to a bag with more dividers, and I've been storing it in the closet after washing it. ● Shipping I will protect it from water damage and ship it via Mercari delivery (probably Nekopos).
