We replace damaged, lost, or broken spheres on any Q-Mark stylus with a 0.6 mm sphere or larger if the stem is still intact.
Step 1: Download and fill out our Q-Mark repair form, print and include in the package with your part.
Step 2: Ship your part to:
Q-Mark Manufacturing Inc.
Attn: Repair Department
30051 Comercio, Rancho Santa Margarita, CA 92688
Step 3: Our styli experts will email you to confirm we've received your part. We'll clean the part and cement a new sphere on it. Most repairs are completed in 1 or 2 days, and cost less than a new stylus.
