This hand specimen is mostly cylindrite by weight, and features some cylinders that are up to 3mm in diameter. Also, some of the crystals reveal their true form, as rolled up sheets of the mineral that only appear cylindrical. The remainder of the specimen is a nearly massive reddish-brown mineral, likely cassiterite.
