Alcohol-based, buff-resistent and quick-drying. The large 250 ml refill is not just a simple refill … it's a true secret weapon. Just like all TRANSFORMER markers and bodies it is equipped with the standardized TRANSFORMER screw-thread. All you have to do is insert the TRANSFORMER pump-valve and screw on an X-change head of your choice and with in seconds you have a real monster marker! The 250 ml refill is available in 3 colors.
