Copper tarnishes through handling (skin acid). Whilst we endeavour to send sheets in very good condition, you may find some of the surface is marked. Remove with Brass Restorer (see below).
Thin copper sheet (0.076 - 0.1mm) is very malleable and can be cut using scissors or a scalpel.
For thicker thicknesses use tinsnips or a fine razor saw to cut sheets 0.5mm+
Our Photo Etching Service can etch in copper if you are planning an intricate design.
