Solder - Kester 63 / 37, 1 lb spool, 0.031" diameter
(63/37 Rosin Core) - ..031" Diameter, 1 lb Spool, contains lead alloy.
Kester 44 Rosin Flux is an activated rosin formula for use in flux-cored solder wire. Kester 44 Rosin Flux has virtually dominated the field of activated rosin core solders for well over four decades. An outstanding performance feature of this flux is the “instant-action” wetting behavior. The high mobility and fast-spreading action of this flux results in more reliable production line soldering.

This is leaded solder. It is advised you use this solder in a well ventilated area as well as employing breathing protection.
Can't imagine building guitar harnesses without Kester solder - nothing flows as well!! Easy to do clean efficient work!
I don't always breathe noxious fumes, but when I do, I breathe Kester 63/37 solder.
