Here is an incredibly beautiful pair of men's Mid Century Modernist style, made of what I believe is brass and enamel or glass. The dark colored glass or enamel is deep black in color. The designer is unknown to me. There are interesting marks on the backside that may help you identify the maker. The top surface is in very good condition, with tiny, tiny invisible to the naked eye, scratches in a few places. however PLEASE NOTE, they ar...e missing their toggle part, which can be replaced. Please see the photos, which clearly show this. Sold AS IS. They measure approx. 5/8 " x 3/4 ". They are from the 1960-1970's. Recently purchased from a retail store inventory that had closed in the late 70"s specializing in Scandinavian jewelry and clothing. They are unmarked, but have an interesting pattern on the back side. They are a nice weight at 11 gm. They need new toggles to make them functional, but they are great little items. Wonderful abstract little pieces of art, for wearing. They are unique, wonderful. A Special find! One of a kind from this collection. I do ship internationally, and to Alaska/ Hawaii, but the fees are dependent on the distance. Contact me ahead for calculations for this, but otherwise standard shipping fee for continental US buyers is listed. Please refer to photos and contact me with any questions you may have! Thanks !
