2" (51mm) thin ball-end head pins. Approximately 0.02" diameter (24 gauge/0.5mm). Approximately 1.8mm ball end. Plated over brass. Silver plate is a thin surface layer of actual silver. Thin head pins are for small-hole beads. April 2014: We have upgraded these pins to a new, more flexible version. Great for wrapped loops!
These are much too flexible. Fine for something very short, and if you don't mind if they will not stay straight.
Plating chips off with any working.
These are very very poor quality. The wire is way too flexible to be useful for making anything with any length to it. Very bent wires, having ordered these int he past, I am truly disappointed that R&T put these out to their customers.
