They are REAL Working vintage cufflinks in a silvery color that were once dispensed in gumball machines approximately 50 years ago. The lighters are now collectors items. They are unused condition and in working order! I have attached them to matching cufflink findings and made sure the flint and wheel still works but I did not light them. (since these are vintage, if for some reason you get one that doesn't work, please contact me for a replacement). The lighters have a screw bottom to (re)fill with lighter fluid - the screw has an o-ring to keep fluid from evaporating.
CAUTION: Now of course care must be given that you don't burn yourself up trying to light a cigarette. TAKE THE CUFFLINK OFF BEFORE LIGHTING.
