I have a box of silver solder brazing rods I bought years ago for a project.
They are BOC EUTECTIC 56% silver.
Flux coated. Lovely to use flux can be removed easily
Selling separate at £15 each or 5 for £60. Message me if you need 5 and I’ll make an add for them.

* please note that this is for a rod or 5 rods and not a box of rods*
