TCC8-L Teslin Laser Sheet. This Teslin sheet has eight micro-perforated 2 1/8" x 3 3/8" Teslin card inserts. The Teslin inserts will remove cleanly from the sheet and when inserted into one of our Credit Card size Butterfly Laminating Pouches it will form a borderless rigid ID Card. The overall printer sheet size is 8 1/2" x 11". A template for this sheet is built into EspressoID software.
