The Transfer pad / Stone Center pad. x2 4-10mm dops and 2-7mm round stones. This tool is used to save some time and headache when dopping round stones perfectly center. In the video I show an example of how quickly I can dop this 6mm round Swiss blue topaz! The transfer pad worked perfectly as intended. Needed to tweak the text a little on the sides to make it more legible, pictures are of updates version. Stack two on-top of each other to use as a transfer jig.
