The best way to store oil colors is with the cap down! This prevents separated oil from rising to the nozzle opening where it will be squeezed out, leaving hard-packed oil paint at the end. The Tube Rack lets you store 21 paint tubes—from 15ml to 50ml— with the cap at the bottom.
The twenty-one-place rack accepts collapsible tubes up to 3 cm (1.125") diameter. The tube rack is made of a special blend of polypropylene that sinks in water, assuring the racks do not float when immersed so they are easily cleaned. Dish washer safe. Easily stackable.
Overall dimensions: 24.5 x 10.5 x 7 cm (9.75 x 4.125 x 3"). Square openings are 3 x 3 cm (1.125 x 1.125")
The Tube Rack ships flat, but is easily assembled in seconds.
