戒指量測與成型棒 — 帶槽木製心軸，美國尺寸1–15，防滾手柄

The non-roll handle makes a huge difference when I'm hammering a band into shape — the stick stays put instead of spinning away. Sizes 1 through 15 are clearly marked, so I can switch between rings without guessing. Exactly what I needed for my bench.

The grooves are deep and evenly cut, so my rings stay perfectly aligned while I hammer. I also love the non-roll handle — no more chasing my mandrel across the bench. This stick feels solid and well-balanced for its price.

Finally, a mandrel that doesn't roll off the bench mid-shaping — the non-roll handle is a game-changer. The hardwood feels solid in the hand, and having US sizes 1–15 clearly marked makes quick adjustments easy.
