The non-stick polypropylene SealPro paint tray comes with a plastic lid that locks onto the tray forming an airtight seal, similar to plastic food storage containers. The lid's "pocket system" displaces 95 percent of the air in the sealed area, keeping paint and rollers fresh for months. One feature has the roller handle set on a rest above the paint reservoir, allowing the roller to remain in the tray when the lid is closed. The inclusion of the painting roller within the sealed tray area alleviates the need for messy cleaning or purchasing new rollers. The reservoir holds a gallon of paint.
