Two types of bristles for different levels of cleaning.
Natural horsehair bristles for delicate surfaces.
Plastic bristles for more aggressive cleaning.
The Seam and Crevice Detail Brush is designed for general cleaning. The Horsehair end is staple set into a durable plastic handle with plastic bristles on the other end making it a tough all-purpose brush. Use the horse hair bristles to dry dust seams and crevices or use the plastic bristles with your favorite interior cleaner to remove embedded grime. The horsehair bristles are soft enough to not cause scratches on delicate surfaces. Make sure to wash this brush after every use and allow it to dry completely.
 
Size: Overal length - 7". Bristle length - 1/2" at each end.
