Soldering iron tip cleaning mesh filter welding solder nozzle cleaner.
This is my first time, using such kind of soldering aid. After I have received it, today, I have immediately tried to using it and it really simplifies a lot the soldering job, keeping the soldering iron bit, clean. A great surprise is that there was no stamped brand on the cleaner body, what generated a cleaner appearance. On sellers advertisement there was an unknown brand. Not so beautiful. I only guess that the packaging could be a little bit more protective but, in all the cases, no damages were noticed on the item and arrived without smashes.
