Joseph ★★★★★

The case is a nice touch—keeps all ten pairs organized instead of rattling around in a drawer. Checked a few with a micrometer and they held to that 0.0002" spec, which is solid for the price.

Eli ★★★★★

I’ve been using these to set up a surface grinder and the 0.0002" parallel tolerance is spot on—every pair I checked matched exactly. The hardened steel has held up to a few drops without any dings or burrs, and the fitted case keeps the 1/8" thick pairs organized by size.

Isabella F. ★★★★★

Bought these to shim up a mill vise and they drop dead flat every time — no rocking at all. The fitted case is a nice touch too, keeps all ten pairs from ending up loose in a drawer. Hardened steel feels solid, no burrs on any of the edges.
