Hand crafted with coordinating fabrics, and fully lined, they are all one of a kind. Because they have adjustable straps, they work well for wheelchairs with either bicycle-type push handles or can be used on stroller style handles as well. The bag can also be easily removed for machine washing. They have a total of 4 pockets, 2 half-width pockets in the front, then two full width pockets. Works great for keeping homework, books, oxygen tanks, fidgets, or crafting supplies, or whatever you need handy. You can buy this Wheelchair Necessity Bag here!
