There's two available options: canvas wraps and metal prints.
Canvas wraps are printed on a 400 gsm poly-cotton blend canvas with standard archival quality of 100 years.. They are 1.5" thick and ship with a saw tooth hanger for smaller prints, and a wire hanger for larger prints.
Metal prints are sublimated onto a 1/16" thick sheet of aluminum and shipped with a float mount. Under normal indoor viewing conditions, these have a Standard Archival Value of 100+ years.
