FAQ
Is this a neck lanyard?
No — this is a no-tail strap worn around your head without a long cord on your chest.
How is this different from the steel wire 2-pack?
This listing uses a tunnel-hole silicone mount. The steel wire 2-pack uses a different silicone + wire construction with two straps per size.
