The first time I order these plugs I took a black pair and a pair of chromed 5 mm, the problem is that I have received one each !!! a black and chrome plug plug, a pair of earrings, a pair of shoes that walk by 2, no !!! I am disgusted, so I said what good are not serious and I would recommend exactly the same so I would have my last pair, well no !!! Because I had to order 5 mm and it sent me 2 mm !!! grrrrrrrrr, the I'm angry, and then I do not want to es ... pfffff returned etc., be careful ...
