Both copper and aluminium rings are fitted with silicone in the inner part which ensures that the hair inside does not get damaged and provides a better grip on the hair. That is very important because nobody wants extensions that fall out. These micro beads stay in place and there is no way they will get loose. The silicone enables great results even for oily and hard to grip hair. Aluminium and copper are both great materials which will not get damaged or scratched when washing extensions and doing regular maintenance. They are made to last for a long time and color will not wear off. Different color options, from blonde to black, ensure that the rings will not be visible because you can perfectly match them to the color of the hair. Size - 5.0*3.0*3.0 mm 1 packagems - 100pc
