Constructed of durable transparent plastic mesh, this bag allows you to easily see all of your supplies at once while keeping them secure. Features a heavy-duty zipper with a nylon pull that glides easily and keeps supplies safely inside. The zipper is stitched, not glued in, for strength and sturdiness over time. Measures 16x21" and has a 1" gusset at the bottom. To keep items secure, thread a zip tie through the zipper and the built-in nylon loop on the side.
