Seller YOUgNeek has restored the cufflinks with matching findings and inspected each set to make sure that they are in working order.
According to the seller:
Each cufflink has a bullet back enclosure so you can slip it into the smallest of buttonholes or the largest and still have it lock into place when you flip the bar horizontally. Each lighter is only 7/8 inch tall by 3/4 inch wide and 3/8 inch thick, just the right size for a cufflink!
We can only hope that YOUgNeek keeps his/her eyes open for some more.
