THESE ARE NOT A SET. YOU MUST PURCHASE EACH SIZE SEPARATELY. Mama measures 11" wide Mini measures 7" wide (Shirt not included) Transfer Type: Puff Screen Print Print Color: Black APPLICATION INSTRUCTIONS You MUST have even and consistent pressure. I test each transfer to make sure they are perfect before I add them to the website. I can assure you that if there was a transfer problem I would not list it. The suggested settings: * 360-370 degrees * 5 seconds * Medium-Heavy pressure * No Teflon sheet (press directly on the print) If you have not used these before I recommend getting a few to work with. Make sure that you can get them to press correctly before taking orders. If the suggested setting does not work you may want to adjust it a little. I CANNOT send refunds for these transfers if your heat press will not work with them.
