I received this as a bonus from THREE. I've used it a few times. There is yellowing and stains on the front and back bottoms. It's made of thick, sturdy canvas fabric. It has a large gusset, and the construction is solid for a bonus item. Size: Width: 30cm Height: 24cm (35cm including the handle) Gusset: 13cm Color: White系 (White-based) Material: Canvas/Cotton Features: Horizontal, Gusseted Damage: Stains/Tears (Yes)
