One piece folders are a smart, protective solution for shipping and storing flat items that don't fit neatly in standard boxes. Ideal for books, binders, catalogs, and framed artwork, these folders fit snugly around your items, reducing shift during transit. Constructed from durable corrugated cardboard, they provide exceptional protection without excessive bulk. All folders are sold in bundle quantities, ship flat for easy storage, and are able to be assembled quickly when you're ready to use them. If you wish to order in bulk, please reach out to us through our contact form.
