I purchased a Wagner paint mate stick years ago. I love the tool. It makes such short work of any room painting / ceiling painting project. It has but one design flaw. The roller core assembly is reeeeeeally easy to throw away during the paint clean up process if you're not careful. Long story short, I did. Very glad ereplacementparts had the part I needed, as no one sells this tool around here anymore. I have two Wagner Paintmate sticks, so I bought THREE roller cores! Thank you ereplacementparts!
