Deluxe Ring Mandrel - My Pick for Measuring Rings - US, EU and Metric

SKU: aluminumringmandrel
I am frequently asked for advice in selecting a Ring Mandrel; this is it! This measuring mandrel conveniently measures in Metric, European Sizes and US Sizes in whole, half and quarter increments. Note that there are 2 flat surfaces - this makes it easier to read the size and just as important, your ring will not get stuck!

This is made entirely from aluminum so it is sturdy but will not break a tile if you drop it on a tile floor (yes, I tested it - lol). It measure 10 inches (25cm).

This is not for forming or shaping, but for accurate sizing.
