melisantelmo Hi @tinyrightbrain, I have wear them in polished brass and they are really lightweight and comfortable for my earholes, but mine may be a little more stretched than yours. In the 3d model, I made the wire of 1,1mm diameter, but the polished finish left it in about 1 mm, that is equivalent to an 18 gauge, a little fatter than the most common ear wire. I hope this information helps you! Thanks for your comment :)
