Great product, just as good as the old stuff from the sixties and seventies. The info on the spool says: DOM 2024 - 01 - 26 which would be Jan. 26, 2024. This is the Date Of Manufacture or DOM which is very important as the rosin in the solder will dry out after a few years or maybe three. Kester 44, .031 diameter, rosin core flux is the best solder you can buy for small projects and printed circuit boards. Don't buy Lead Free or any other water based types. ### ⭐⭐⭐⭐⭐ The best! I'm never settling for cheap solder again *by on Reviewed in the United States March 16, 2024* I've been using cheap generic solder for a while, and I thought my soldering technique was poor because I kept getting cold solder joints and had to use a lot of flux. This stuff flows effortlessly and leaves nice, strong, shiny connections. I did a quick solder job and every solder joint on the PCB and my wire connections looked flawless on the first attempt, I didn't even need additional flux. I threw away all my cheap solder when I was done and I'm strictly using Kester solder from now on. ## Frequently Bought Together - Kester solder 44" Rosin Core #66/44 .8mm 1 lb.
