Bushings are the unsung heroes of pen turning — they're what tells you when to stop cutting, ensuring the turned blank matches the diameter of the pen kit's metal components for a perfect seam. The wrong bushings produce a pen with a visible mismatch at every joint, so getting the right set for each kit you turn matters. We stock matching bushings for every pen kit family in our catalog: slimline, Sierra, Jr II, bolt action, cigar, Astra, Regency, and dozens of others. If you're unsure which bushings go with a kit, check the kit's product page — we list the matching bushing reference for every kit we sell.
