AKOAK Portable Antique Style Mini Copper Caliper Double Scale 0-80MM Metal Caliper for Measuring Gemstones and Jewelry Components

It's just what I was looking for. It's small and sturdy and has small and precise lines for measurement. I like that it measures standard as well as metric. I inferred that the tab screwed down to hold a measurement, which it does not but the pieces fit well so it doesn't slide loosely.

We've had them all. The digital ones that go bad after a while, the ones with the wheel that won't stay in place. This is simple and easy to use and read.I only wish it were a little longer because it gets lost in my pencil cup, but it's a good product.

Not at all accurate. Square part is not square or level! This is a pointless tools. Do NOT buy this!

Not as sturdy and firm as I thought it was going to be

A remarkably accurate instrument and very sturdy. Perfect for in the pocket yet accurate measurement. I bought two and are very pleased with them.

Smooth sliding, well machined for price. Exactly what I needed. Cute little functional tool.

Needed to make sure I have the correct size closure for my hand-beaded bracelets. Also when leather is braided it really get bigger fast. Soooo . . . I need to have a size to make sure I’m on the right track in finishing my pieces. I did not want to pay for a calibration tool that I would have to add batteries to. Old School is Better‼️😎

Looking good high end finished. Love it!!
