All the pieces of Tisserlitine 001 have a flat slab-like form with a knobby exterior. The exterior of the stones is a medium brown color. The interior of Tisserlitine 001 is a tan to pinkish hue with whitish, light gray, and dark gray clasts. Small metal grains are seen in the meteorite. Some alteration and replacement of minerals is noted in Tisserlitine 001 and seems to be the result of hydrothermal processes.
