MUJI Foldable Water-Repellent Boston Bag! A foldable Boston bag. When unfolded, it's the perfect size to fit on one side of a 36L MUJI hard carry case. Use it as a sorting case when you go on a trip. On the way back, when you have more luggage, use it as a Boston bag. It comes with a belt that allows you to set it up on a carry case. The fabric uses recycled materials and is partially water-repellent. A convenient foldable Boston bag that can be used as a sorting case inside your carry-on bag when you leave, and as a carry-on bag on your return trip when you have more luggage. The zipper can be fully opened, and it fits perfectly on one side of a MUJI 36L hard carry case. By making the inner lid with a zipper in two ways (mesh and the same material as the side fabric), it is designed for ease of use, allowing you to separate items when sorting. It's a packable design that can be folded and stored compactly, so you can carry it as a sub-bag. No noticeable damage, and it can still be used for a long time!
