2.9mm Nano copper with silicone color of choice 1000pcs

We offer special copper Nano Micro rings with silicone liner and an outer diameter of 2.9 mm. The inner diameter is 1.9mm and the length of the rings is 2mm. Copper Nano rings have a special shape that eliminates the formation of sharp edges after snapping and creates an almost invisible secure connection. Mirco rings are used for hair extensions using the Ring method. The color of the copper rings holds very well and does not peel off like with classic aluminum rings.
