You asked, we listened! Just added:
Thick, oversized hair elastics - these are great for men, or anyone with larger wrists. The large size won't pinch your wrist! Thick elastic is completely covered for comfortable wear. No metal. In a convenient 10-pack for $5.
Each measures about 9" in diameter, un-stretched. elastic is about 3/4" wide, and about 1/4" thick.
