The Mixing Mate Paint Lid can be used to mix and store finishes such as paint, polyurethane, and stain. It clamps onto any standard quart container, creating an airtight seal that prevents spills. You turn a top-mounted handle to stir the contents and dispense them through a thumb-activated pour spout just like the one on the syrup container at your local waffle house. Available in quart size.
