Description
We use core wires made out of carbon steel because carbon steel is not only stronger than other metals, making it more resistant to bending, but also carbon steel core wires grip bristles tighter. Buying our quality brushes in bulk packs saves you a lot of money. Our low unit price plus shipping through Amazon is less than gas money spent to drive to a store 30 minutes away.
