Thank you for viewing. Brand new, unused, foldable Boston bag, 36L. 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 it to be carried on a carry-on. The fabric uses recycled polyester and is water-repellent. 【Recommended Points】 ・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 when you return with more luggage. ・The zipper can be fully opened, and it fits perfectly on one side of a Muji hard carry 36L. ・By having two types of inner lid fabric (mesh and the same material as the side fabric), it is designed for ease of use, allowing you to separate items when sorting. ・Packable design allows it to be folded and stored compactly, so you can carry it as a sub-bag. Please refrain from price reductions. Thank you. Features: Compression possible, carry-on allowed
