1.26 USD
Very useful solder wire. I prefer the thickness of 1.5 millimeters for general use, doing the solder job more easy. The item arrived in less than a month, what is very good. Seller assured that It came inside a cardbox, protected by a convenient layer, avoiding damages and brokens, during the transport. The only cons is that the price can not be considered fair, probably to its heavy weight, that have contributed to made the price goes to stratosphere. In all the cases, it was the time of buying a replacement part and there are no regrets.
