Megacast Stainless Steel Ring Sizing Mandrel Sizes 1-16

This product is amazing especially for its price! The quality is amazing which I was not expecting, definitely recommend buying! It’s super easy to use and read!

Heavy and solidly built. Just like jewelers use. No guesswork.

Awesome sturdy heavy

Used this to get my sterling ring back to round. Very easy to use.

Nice tool but using it to resize rings will scrape off the numbers.

Had to return two other brands because the markings were impossible to see and one came with the groove in error. This one does not have the groove, is solid round, accurate, and has black, easy-to-read markings. Everything I wanted. Very nice and highly recommend!!

I love this not only can this be a ring sizer it can also be used to straighten rings out.

First time using a steel mandrel. Works so much better than the plastic ones as you can use a hammer to harden the wire to make the rings stronger. I really liked the shape and heft of this one and markings are easy to read. This was shipped quickly. Thanks!

Used a long side a small stainless hammer to size a ring. It worked well. Sizing is accurate

This has a very nice weight!
