This self-adhesive photoluminescent (glow in the dark) tape absorbs and stores light from any light source. Should the external light source be removed, the tape will immediately start emitting its own. There is no limit to the number of times the tape can re-charge and glow.
Ever launched your Decimator or BFG into a bunker then had to embarrassingly ask your team mates to cover you whilst you crawl around in the dark looking for it again? not exactly ideal is it. Well one simple strip of this really hard wearing glow in the dark tape can solve that instantly. Use a permanent marker to write your name onto the tape and then it's also a really easy way of identify who the (previously identical) grenade belongs to. Grab a roll and share it around your team, they will definitely thank you for it.
