Easy-to-use tool for tightening prong settings or setting stones on earring
studs with just one tap. Stones will never be chipped or cracked
because pressure is distributed simultaneously and equally among the
four or six prongs. May be used to set stones or simply tighten them.
Includes urethane post earring base (holds up to 12 studs) and five
tools (2.0 – 3.4mm, 2.8 – 5.2mm, 3.2 – 6.6mm, 4.9 – 8.6mm, 5.6 –
10.0mm).
