Uniqueen 27 Piece Red Plastic Ring Sizer Finger Gauge Kit Tool Measuring Device for Rings Diameters Jewellery

It does the job it's meant to do, and it's quite strong too.

Bought for charity shop selling jewellery,excellent price, look reasonable quality

The set I got went from size 18.2 to 18.6 ... the inbetween sizes of 18.35 and 18.53 were not there. It was disappointing as my size was somewhere in those sizes. Either the set was incomplete or the product is not very good / useful.

Good ring sizer
