Valtcan’s keychain storage canister is longer than most, so it can store toothpicks, rolled up dollar bills, pills, or even a AAA battery inside. It’s made entirely from titanium, and has a waterproof O-ring seal. Measures 3″ x 0.6″ outside, and holds items up to 2.5″ x 0.45″ inside.
This carabiner looks substantial, but weighs just 14 grams thanks to its titanium construction. It has two locations for hanging keychains, a sturdy and smooth spring belt clip, and packs in philips and flathead screwdrivers, wrenches, a 1/4″ hex driver, and a bottle opener.
