The Shur-Line flexible lid is designed for closing, filling and storing jars of water-based paints or stains. Because it is made of silicone, the lid is easy to clean and can be reused. It has an airtight seal that keeps paint fresh and can easily withstand tilting and shaking. The flexible spout reduces pouring losses, and the vent on the opposite side of the spout protects against unexpected splashes for trouble-free pouring. For storage, the spout of the lid folds into a recess, making the surface flat for easy stacking. In addition, the protective cap on the spout prevents the paint from drying out inside the jar.
