Chemtronics, 80-4-10, Desoldering Wick, 10 ft., 4, Copper, Rosin

I have been soldering for 30 years, at first on a manufacturing line to DOD ISO standards. This was all they used. Later, for various types of guitar repairs. If it was good enough for rocket parts, good enough for anything else. Does what it is supposed to. Wish I could afford an air suction solder repair gun, but that’ll never happen, lol, so this is the next best thing. I have them in about 7 different widths.The fact that you can buy them on here these days in a pack of 4, is great, versus longer ago where you had to buy a box of them from a specialty supplier, just to get them at all.
