If you're looking for sturdy bins, you'll get exactly that with WISHPOOL Collapsible Storage Bin Baskets. They are made out of a strong canvas material. They come in white but would love if they would also come in a black or navy blue. I would definitely buy several more! I am using one for art supplies and the other to keep my workout bands and stretching straps. Both are very convenient as they have handles and I easily can transport them to the gym or workshops.
