- Brand: TAURUS - Product Name: Achikochinon - Contents: 5 pieces - Purpose: Toilet training - Features: Prevents dogs from misbehaving - Expiration Date: 2027.08 I used 3 of the 5 pieces. My dog got irritated by the unpleasant smell and kept picking them up and throwing them around, so I'm selling them... haha. 2 pieces are unopened and new, but since they are used items, I will sell them to someone who understands this.
