Yes. one of the sides are just plain. Maybe where the label would have been.ORIGINAL: Poison_Us
Cryptic, No, not all poisons have ribs. Ribs are most common in English poisons, but not all. Some US poisons do have ribs, such as this, but most US poisons have other textural characteristics. Is the one you got there ribbed on 3 sides with the one in the rear plain?
