Vintage round brown cufflinks

Wood imitation cuff links. There are no marks and these could be hand made. They are light weight and seem to be made of resin. The silver tone hardware has a bit of tarnishing and the back of the circular pieces have a few marks. This is shows in the pictures. I also want to point out 2 small scratches on one of the cufflinks and this is shown in the last picture. The circular piece is approximately 2 cm in diameter and both pieces are not completely identical.
