A slightly used 14K Gold Plumb Solder Kit originally purchased from Frei and Borel/Otto Frei. It is item # 800-5555.
This kit contains four different gold solders, one piece each of 14K yellow gold easy flow, 14K yellow medium flow, 14k yellow hard flow and 14k white easy flow. Medium appears to be used the most, and the white easy hasn't been used at all.
Please feel free to contact me with any questions. Thanks!
