Super easy paint touchup
After you finish painting a room, pour a little of the left-over paint into one of these small BIBR touch up bottles. One for each color. The plastic bottles contain a small applicator brush inside (plus a marble to shake/stir the paint) which makes it super easy to break it out to touch-up as things happen. Gareth Branwyn suggests keeping the touchup bottle in a drawer in the room itself, making it a no-brainer to grab when needed. Touch up will never happen when the paint is at the bottom of a can in the basement. — KK
