戒指尺寸量棒 — 金屬量尺1支，霧面處理，男女適用美國尺寸

I've been using this mandrel every day for a week and the US size markings are spot-on, which saves me so much guesswork when resizing customers' rings. The metal is hefty enough that it doesn't wobble on my bench, and the dull finish actually helps me see the sizing lines clearly without glare.

I’ve used it to size a few rings for friends and the US markings are dead-on accurate, which saves me the guesswork. The metal is hefty enough to stay put on my bench, so I don’t have to worry about it sliding mid-measurement.

The dull finish is honestly a nice touch—rings slide on smoothly without scratching, and the etched US sizes are sharp and easy to read. It’s solid enough to hold steady even when I’m tapping a stubborn band down, which makes sizing both men’s and women’s rings a quick job.
