Available in SP or GP. 28guage (0.5mm) wire. Easy on the hands but firm enough for twisted "Tiara Branches". We tried a few different wires in our "Tiara Test" and found that this wire is more pliable than the Plated 0.4mm wire we tried, but just as strong. It is also great for wire-wrapping tiara bands, etc. The colour is brighter than some wire that we tested, preventing the finished piece from looking dull. Results of the test? We think we have a winner.
