Nice Complete Sizing Set
I was pleasantly surprised by the quality and complete sizing parts to the set. It is nice quality and complete with sizing rings to try on your fingers and sizing rod to test size of any rings you have. The set is all metal, not plastic and arrives in a reusable storage bag.

Great ring sizer, would recommend
Great item at a great price. The metal rings on the ring sizer feel much more realistic compared to the plastic ones. It allows you a good sense of an idea on how a real ring would feel. It was helpful to use multiple rings on one finger to see how sizes would differ when stacking multiple rings. The rod is very helpful identifying sizes of rings that you already have. Something I would have no idea about otherwise. Very durable and perfect weight similar to regular rings.

So important to have around!
It's always difficult to know what size ring to order when you can't purchase in-person. I have multiple rings which fit great but what size are they really??!? This thing works great!! So the ring for my middle finger is a 7, my right ring finger is a 6 and my left ring finger is a 5 - see? You need this in your life!! You'll have these forever and it's dirt cheap in my opinion. Just order!!

Very Accurate and Handy!
This kit helped me a lot with ordering rings online. I measured all the rings I already have, and they matched perfectly with the sizing on this tool, which gave me confidence when placing my orders. The mandrel and sizer set are sturdy, easy to use, and very accurate. If you buy rings online or want to know your exact size, this set is a must-have. Great value for the price!
