Custom Coaster or Catch-all Additional Image/coloraddt_image_custom
For additional images on your custom coaster packs. Order one for each additional image you'd like, in addition to your custom coaster order. (For example, if you're ordering a custom coaster 2-pack with two images to be printed - one per coaster - order one custom coaster 2-pack PLUS one custom coaster additional image. If you're ordering a custom coaster 4-pack with four images, order the custom 4-pack plus three custom additional images).
