BENECREAT 24Gauge/0.5mm Bare Copper Wire with Oil Coated, Tarnish Resistant Copper Wire for Jewelry Craft Making, 198 Feet/60m

Even though I purchase 0.5 mm these are more like 0.4 mm. They are strong and easy to shape.

But it has some form of coating on it.

Did exactly what I needed it too

excellent product. I bought this to wire wrap some stones and pottery. when it first arrived I was concerned it would be a little flimsy and there wasn't much wire, but I was pleasantly surprised at the sturdiness of the wire and how much there was. very flexible and exactly what I needed. brilliant value for money.

Weaves well; can create some lovely creations
