We have had this popular keyhole ear weight design made in dark, almost black Arang wood with brass dotwork ends. They are not very heavy, so are best described as ear hangers. They only weigh about 14g each.
They only come in one size at the moment, listed below as 12mm. But they will fit any stretch above 12mm. 14mm and 16mm are ideal, though of course you can wear them in larger stretches as well.
Unless clearly stated otherwise,
the price is for one piece, not a pair.
