Product Description
The Amy Kate’s Workshop Bracelet & Ring Sizer Combo is designed for makers and resellers who need accurate bracelet sizing and a portable ring sizer they can take anywhere. The round and oval bracelet sizers use a stepped mandrel design to measure true inner circumference from 5″ to 9.5″, which is more accurate than flat rulers or tape and better reflects how a bracelet actually fits when worn. This makes it ideal for sizing bangles, closed bracelets, and finished pieces where precision matters. The included ring sizer is compact, lightweight, and pocket-friendly, making it perfect for occasional ring sizing at estate sales, swap meets, craft fairs, and resale situations. Unlike large steel ring mandrels that are heavy and meant to stay in a workshop, this ring sizer is easy to carry and quick to use when you need a fast, reliable size check. It is a light-duty tool, designed for convenience and mobility rather than high-volume production use. Together, these tools create a smart, space-saving sizing set for jewelry makers, resellers, hobbyists, and craft vendors who value accuracy without unnecessary bulk. Both pieces stack neatly, store easily, and are designed and made in San Diego, CA by Amy Kate’s Workshop, a small family-run business focused on practical, well-designed jewelry tools.
