📏 13-Inch SE Ungrooved and Marked Ring Mandrel - JT-SP212 Review

This is just HARD for me. So I still have to use my old one (which is hard to read). Husband likes it. We think we can use it to take down a robber if need be!

Nothing to test other than that it was durable, had the size increments I needed, and was exactly what I was looking for. Good product. However, I would like it to come in a cloth pouch to keep for storage and travel purposes. The plastic tube it was in was crushed and broken. 😱

I have recently inherited jewelry from a family member and ordered this core to determine my ring size. This is a really nice heavy duty stainless steel mandrel. It comes in a plastic case as shown which is very handy for storage! The measurements seem to match the rings I have where I know the size. I highly recommend this device if you are looking for a quality calibration tool.
