Simhevn 27-Piece Ring Sizer Set — Stainless Steel Gauges & Two Sizer Belts

Complete three-piece measurement solution: This set arrives with a ring sizer measuring tool, a finger sizer mandrel, a full ring gauge collection, and an extra sizing tool to handle most jewelry sizing tasks. It’s designed to give you multiple ways to determine ring size accurately.

27 stainless steel gauges: The kit contains 27 metal ring gauges covering US sizes 0 through 13, including half sizes, crafted from stainless steel for a smooth feel and long-term wear resistance. The metal gauges slide onto rings or act as reference pieces when resizing or verifying sizes.

Two reusable sizer belts: Included are two plastic sizer belts for testing sizes directly on the finger — one features a built-in magnifier for clearer scale reading, and the other spans sizes 1–17 US. Both belts are reusable and adjustable, making it simple to compare fit across fingers and time of day.

Additional accessories and finish: A polishing cloth is provided to keep the metal pieces clean and looking professional. The mandrel and measuring tools have a silver-toned finish and solid construction, suited to both shop use and crafting benches.

How it’s used: Slide gauge rings over fingers or onto existing rings to determine size, wrap a sizer belt around the finger to test comfort and fit, or use the mandrel to measure ring inner diameter for resizing jobs. Compact and straightforward, the tools remove guesswork from sizing for both buyers and creators.
