This paint rack is made out of high quality maple plywood and is delivered unassembled. The paint hold 35 dropper bottles. This is a conversion kit that includes 35 15ml dropper bottles, metal agitators, a funnel and the paint rack. It is an “all in one” package to convert your paint pots over to a refillable dropper system. Dropper bottles reduce the change of your paints drying out and makes measuring colour mixes much easier. The rack can be spray painted to match the colour of your storage area.
