The storage bins are made of odorless, three-layer composite soft and strong non-woven fabric which promotes ventilation and protects your stored items. The containers have plenty of space to hold your quilt, blanket, pillow, stuffed animals, out of season coats or other clothing. The handle is sewn with two layers of thick fabric to double the load-bearing capacity. Reinforced seams also add strength, are less prone to breakage, and last longer. The storage box is equipped with a sturdy #5 stainless steel zipper for durability. The two-way zipper slides easily along the closure when in use, no matter how full the storage bags are. You can quickly see what's stored inside the container in the front transparent window.
