Color: Black, Set of 3 Material: Aluminum alloy With back magnet USB rechargeable Type-C cable included 6W Bright, 500 lumens 4 modes Long press for strong light Strong light Weak light Strobe With carabiner With keyholder carabiner Bottle opener Very bright! I bought these with friends, but I bought too many, so I'm selling them. Apparently, unlike the ones at the nearby OOO center, the battery capacity and brightness are also amazing. Highly recommended! ^_^ I use mine attached to a wire keyholder from the 100-yen store. It's very convenient!
