This set is now in my Etsy Shop. The acorns caps are real. I found some interesting folklore on the acorns. They were used as a divination tool on Halloween night. Lovers would take 2 acorns and each would place 1 in the same bowl of water. If they floated together they would marry. If they floated apart they would not and if they sunk death! Mine are not ment for this game but I thought the folklore was fun!
