These Hush Buttons are the quietest brush buttons on the market! I make them, by hand, in Minnesota. New, for late September, 2025, these have a top cap of the hardest rubber yet, designed to grip tighter in place in hot weather. The rubber will not begin to harden, until temperatures fall below zero degrees, making them quiet in cold weather. This dual rubber compound, the only buttons on the market to feature this, is a must to both get a firm grip on the string and stay quiet. In addition to deflecting brush, the purpose of brush buttons, these also act as string silencers. At around 26 grains, they're light weight and won't slow the shot. I ship, with tracking, for multiple pair orders, and large envelope, no tracking for single pair orders.
