This is a drawstring bag I purchased at Flying Tiger. It's not a heavy-duty item, and is intended for everyday use. It's a bit cheap, but it has plenty of storage space. It also seems to have a simple coating on the inside. It has many pockets. I've only used it a few times. It didn't suit my needs. If you can make good use of it, please consider purchasing it. Please purchase if you understand that this is a used item, as it has been stored by a private individual. Shipping will be via either Rakuraku Mercari or Yu-Yu Mercari. I will fold it up small for packaging.
