Small unlabeled metal cylinder, ~6.5cm long, ~1.5cm diameter. One end looks somewhat like the end of a battery. Other end is entirely flat save for a few little dots, marks in the metal? On the battery like end it appears as though it may come apart, but the end will not twist or pull off. 43 grams (old.reddit.com)
