As a standard, we do not individually sleeve prints to conserve materials and plastic. This additional charge covers the cost of materials to have ALL of your prints sleeved within your order. Offers extra protection and improves display. 11"x17" prints get chipboard backing and a plastic sleeve. 5.5"x8" prints will just have a plastic sleeve. *Note: if you do not purchase this extra charge, prints will still be securely wrapped in paper for transport to your shop.
