One of the first creations in our Detail line of brushes, the Triangle brush not only paints corners with precision and accuracy, it works great for cutting in next to trim as well!  
We designed the triangle brush for wall corners. The triangle shape is designed to fit perfectly into the hard to reach corner of the wall - the area where your roller can't reach. Never struggle getting into the corner again, we promise it will be a 1 stroke job!
 
EASY everyday application! Unique shapes for every project
 Patented hourglass handle design - no more sore hands!
 25% more proprietary white filaments in each brush head
 Maximum pick up & release of paint through micro-tip flagged filaments
