This unique Mad Hatter coin flipper is based off the "Heads" side of actual larger Mad Hatter coins I had made in RL awhile ago (I also call it a lucky two-sided coin). This is compatible with male avis only I will make the female version soon. Please Try before you Buy and if you like the product please leave a review. Thank You :). Trigger words for the coin are CoinFlip and CoinRow. (Avi used in the product demonstration my male avi Ozzie).
