Selling pitons. Apparently they are made in the U.S.A and manufactured to military specs.
There is no markings on them so I can not confirm what the specifications are.
$10 each, plus $1 each to ship (one side says "Live Hard..." and the other says "but don't be a dick"
length = about 3 3/4 inches. Even when it's cold!
Buyer assumes all risk if you choose to place these.
