Empty Tubes are the perfect solution for preventing leftover mixed paint from drying out. These white lacquered aluminium tubes are also ideal for those who like to create and store their own paints. The screw caps attached are easy to open and keep colours fresh when not in use. Empty Paint Tubes should be filled from the open end (not the end with the cap). This open end can then folded over and pinched tight to seal the tube. If squeezed with care, these Empty Tubes can be reused.
