Here is a nice cufflink and tie clasp set that is marked Flex-Let Quality USA on the back of the tie clasp. I believe the metal is brass but I would describe it as gold toned in color. The clasp is 2" long. The Mason insignia is 1/2" by 1/2" if you measure the red glass it is mounted on. The insignia on the cufflinks measures 5/8" by 9/16" if you measure the red glass. The insignia is made into the glass on the cufflinks whereas the insignia on the tie clasp is an applied metal piece. Beautiful set in wearing condition. The 3 pieces weighed together weigh 21.3 grams.
