I think I've reviewed these in the past but they are my favorite thing to make. They are stainless steel so they don't fade unless they are in direct sun. You can put any sublimation print on them (peel off the plastic first) w an Epson 15000 sublimation printer or an 8550. They are 10" not 8. So you need the bigger printer.
