Designed by HELLO! LUCKY We love to have pun! Letterpress printed and foil stamped at EP MFG. Packaged in a plastic cello with a kraft envelope. Dimensions: A2 (4.25 x 5.5 inches) The foil stamping process is hot- about 160 degrees hot! First, a copper relief plate is plugged in on the press bed, so the plate can get heated. Then, when the foil rolls over the image and the press, paper and plate collide. Magic! Shiny fun!
