The Birchwood Casey Angled Brush 3-Pack includes a Bronze, Nylon & Stainless brush.
Stainless brush: use on hard metals
Bronze brush: all-purpose brush
Nylon brush: use on delicate areas
These brushes are angled for deep cleaning and durable enough to hold up against corrosion and solvents
Includes two brushes with stainless steel wire bristles and one with less aggressive nylon strands.
Use only on interior surfaces or prior to polishing and refinishing as these bristles will scratch most gun steels and surface finishes
