Norton Medium Disposable Paint System, 25oz. The Norton Paint System with its distinctive unitized construction allows for spraying in any position with or without the hard cup. The easy-to-assemble system ensures a consistent spray pattern, convenient storage of paint as well as easy and clean disposal of the entire unit. The Norton disposal paint cup eliminates the problem of gunked up threads because each unit comes with a fresh set of threads. The only reusable component to keep track of is the hard mixing cup with pre-printed measurements, so there are no inserts to keep track of either. The unitized Lid/Liner assembly is guaranteed never to come apart during disposal which eliminates the hazard and mess of spilled paint. Or, it can be securely sealed with the plug for use in future spraying of the remaining paint. No matter how you handle it, the unitized leak-proof Lid/Liner assembly is guaranteed to remain securely sealed during disposal or storage. This is a medium kit size with 48 units in a box.  21647
