You've worked hard perfecting your project, and the finishing stage is no place to take chances. These paper strainers feature a medium mesh at the tip of the funnel that eliminates virtually all unwanted particles and solids that would mar an otherwise flawless finish. Just pour your finish slowly through the filter into a separate container, and let the strainer do its work. Ideal for salvaging finishes that have skimmed over during storage. Compatible with our Finish Strainer Kit (40321, sold separately) which includes a metal stand to hold the strainers.
