Must be heated in a cartridge heater. Suitable for all 100 ml cartridge heaters. Sugar wax liquefies at a fairly low temperature, therefore the sugar resin cartridges are taped to prevent leakage. Please remove the tape before using the cartridge and put the cartridge away upright after use.
the package (how they closed the patron)did looked like some home made version, but at the end turned oit a very good quality.
