Includes an ID slot that flips up when the wallet is open. Sublimation areas are on front and back. Sublimation area is 3 13/16" x 4 3/16". You'll want to make your design with a border roughly 1/16"-1/8" larger than the design area to ensure full coverage. ***PRESSING INSTRUCTIONS*** Press the sublimation area with the transfer paper face down on top of the substrate. Make sure to hang the non-sublimation area off the press so it doesn't melt! You can also use heat tape to help protect the black area of the wallet. Press with medium-heavy pressure at 400 degrees for 60 second. **Time/temp recommendations are just a starting point. Please test your own equipment for the correct time and temp for you.
