Once you remove TheMagicTouch WoW or TheMagicTouch T.ONE transfer from the shirt you need to seal it with TheMagicTouch T.Seal. TheMagicTouch T.Seal has special coating that locks the toner to the fibers of the shirt. This helps prevent the transfer from coming off when you wash the shirt. We sell TheMagicTouch T.Seal by the sheet and is REUSABLE from 350 up to 500 presses.
