This is a tote bag with plenty of storage. It has two pockets on the outside and many inside. The gusset is about 18 cm. As shown in the photos, there are some stains, but I think they are hardly noticeable. This bag can hold a lot, and can fit almost everything you need for going out, such as diapers and baby bottles. In addition, it is useful for various outings. It has been sterilized, but please understand that it is a used item.
