STARTIST Felt Stem Washers vs Felt Valve Washers

Buy the STARTIST pack if you want a small, cheap set of white felt washers to keep a student trumpet or cornet playing and don't care about material specs. Buy the A80 if you are repairing instruments regularly and want 100% wool felt in the correct 1/2 inch outer diameter, with color options. The STARTIST washers are cotton, 1.8 cm (about 0.71 inch) across, and come 10 to a pack, so they are a general fit rather than a precise one. The A80 is sold in dozens or hundreds only, which is more than a single player needs.

• Choose the STARTIST pack if you need a handful of white felt washers for a student horn and want a simple 10-piece set.
• Choose the A80 if you repair or service brass instruments and want 100% wool felt washers in a consistent 1/2 inch size.
