TONER / Spray Paint Can


Normal spray paint needs one can for each color, which is not that eco-friendly and not storage wise. On the other hand, rarely used color may dry out and block the nozzle.

TONER is a spray paint can that combines changeable cartridges. Use cartridges of three primary colors - cyan, magenta and yellow, TONER is able to mix most colors except black, white and metallic colors.

Each cartridge connects to the can through a valve that can be controlled separately. Besides ink, there is another can that contains high-pressure gas as propellent.
