Rubbermaid Paint Buddy

Rubbermaid Paint Buddy:

"The Rubbermaid Paint Buddy is a touch-up paint roller with onboard paint storage. After painting a room, the user stores excess paint from the project in a Rubbermaid Paint Buddy and labels the cap with room and color information. Later, when a wall needs a minor touch-up, the user simply removes the clear cap, opens the valve and applies the paint to the area with the built-in roller. When finished, the valve is closed to seal the bottle and the roller is either cleaned or replaced."via Boing Boing

this might be the coolest thing I have ever seen that I would go to Home Depot to purchase...
