Iron-on transfer Size: 9.5 cm x 6.5 cm The iron-on transfer is borderless and comes to you on a transfer film. A detailed instruction manual is also included. Oeko-Tex Standard The transfer film can be removed hot; do not leave it on the iron-on transfer for too long after ironing. Important! My iron-on transfers adhere excellently to smooth cotton fabric (such as T-shirt jersey, etc.), according to the printer, also on blended fabrics. It is very important that the garment on which the iron-on transfer is applied can be ironed at least at level 2 (the symbol that must be on the garment's label is an iron with two dots).
