We offer special copper rings Micro ring Nano with an outer diameter of 2.9mm. The inner diameter is 1.9mm and the length of the rings is 2.0mm. Copper Nano rings have a special shape that eliminates the formation of sharp edges after snapping and creates an almost invisible secure connection. Micro rings Mini are used for hair extensions using the Ring method. The color of the copper rings holds well and does not peel off like classic aluminum rings.
