Cuff Links and Tie Clip Vintage Pioneer

This listing is for a beautiful matching set of 2 Pioneer cuff links and tie clip. The mountings in each cuff link and in the tie clip are very smooth and have the appearance and feel of mother of pearl, but I can't verify this. Each item is in fantastic vintage condition! The cuff links are oval shaped and measure about 15/16 by 13/16 inches. Each is engraved with the maker's name, Pioneer, on the bottom. The tie clip measures 3/4 inches long. Circa 1960s.
