Titanium Lanyard Rings
The small rings can be used as an adjustment to change the length of any lanyard. The smaller rings fit tightly around gutted or ungutted paracord and serve well as an adjustment point when you have a lanyard around your wrist. You could slip the lanyard around your wrist and slide the ring(s) right up to your wrist. The larger rings are nice to use as an attachment point to hang from a bag or a key chain.
The small rings are 10mm in diameter, the center hole is 5mm in diameter, and they are 2mm thick. The large rings are 15mm in diameter, the center hole is 9mm in diameter, and they are 4mm thick.
