The sting is really copper completely, checked by the jams, all over the fuse is copper, the only inner diameter of the sting is 0,5mm larger than the usual metal stacker. But it gets into a soldering iron and a soldering station perfectly. Thank you for the fast delivery and quality!

Everything is super, it came as it should, it remains only to prepare the sting, + such a sting, then you can sharpen the file for yourself and it will be convenient to solder to The seller is a huge thank you)

Arrived today in consolidated package-pupyrke with other lots. Price and quality are the tinned, look like they are in soldering/распайке, if that will add a review.

Excellent stacks came up perfectly, Ludot well, the magnet does not stick apparently made of copper. Came quickly about three weeks. How long they will not know.
