I was very happy about the mission of these keyrings. Those like me who is too stupid to realize how big 20mm are: which is very small. Namely, smaller than normal keyrings. Stainless those things are not the way, because I have taken them to the sea. Not all, but some. However, these criticisms are not the fault of the seller. He has done everything right. Rather, I'm to blame themselves, with my exaggerated expectations. The shipping was super. Many Thanks. You may then go on here.
