Considering shipping costs, it might be tightly packed using Mercari delivery. The front of the backpack is water-resistant (though the zipper area isn't waterproof), but something seems to have spilled inside. I washed it thoroughly with baking soda, but a faint stain remains. The exterior appearance isn't noticeable, but there are traces of stickers on the surface. I've tried oil, neutral detergent, and hand cream, but they haven't completely come off. This is for those who can handle it at home. Thank you. It's black, but I'll also include a harness, though it's a small one. The length should be for children. It can be used with any backpack. - Design: Anpanman, Kokin-chan, Dokin-chan, Baikinman, Horrorman, etc. - Color: White, Red - Straps: Adjustable back straps - Material: Synthetic leather Thank you for looking.
