This Montessori-inspired wooden memory game features 12 hard wood pieces hand stamped with 3 different dinosaurs including a t-rex, stegosaurus and an apatosaurus. The set comes in a drawstring unbleached cotton muslin bag for easy storage. Each piece is hand stamped with AP certified non-toxic ink and painstakingly hand painted using nontoxic professional grade paint. The pieces are then sealed in our homemade beeswax wood polish, which ensures the longevity of your game! These games provide an excellent way for your child to exercise their brain and have fun at the same time. Research has shown that playing memory games improves memory capacity and can encourage the player to practice abstract thinking. Use the game pieces to practice animal recognition with your child! Each piece is 2″ in diameter and 1/4″ thick. Not recommended for children under 3 or those that mouth their toys. Parental supervision is required.
