I have used these toner sheets with my punches and then inserted the film in a sandwich of heat resistant non stick sheet, punch out with toner side up and then a sheet of foil on top of that with another heat resistant non stick sheet to finish the sandwich. I then stick the whole thing in my heat press and press for 6 seconds and my foil project came out absolutely perfect.
I have the Anna Griffin Minc Machine and wanted to have extra toner sheets for my die cuts. I saw these and ordered them. I love them, they run through my cut - n - boss machine like a dream. They are also in assorted sizes which make it easy to decide which one to use.
