This is a super cool new process that lends it self to CLAIRS vibrant colors. The process is created using a die-sublimation process in which the inks are transferred and then heated onto a special type of metal that locks in the color, gloss and vibrancy! The smaller mini's on metal make a great statement, and come with hanging hardware on the back and are ready to put on the wall as soon as you get it. They look great just as they are- no framed needed. Or, If you are looking for a real stand alone vibrant art piece, we can do a custom size if you choose! This is a great option if you have a lot of sun, as they are more UV resistant.
