Copper Tongs from Beadsmith.

For those who solder, pickle, or condition and alter the patina of your metal.
Using ordinary metallic tweezers and tongs in a pickle solution is a definite no-no. 

Beadsmith Copper Tongs are a good length, measuring 225mm, and have a curved tip for clearer gripping. They are made specially from 100% copper to allow safe use with pickling solutions.
