Some words flip to a word that means the opposite–"good" flips to "bad"–and some words take poetic license with the idea of opposite–"dinosaur" flips to "chicken." Create a poem and flip all the words for surprising fun. A great way to build creativity and imagination! For ages 5 and up. This kit contains over 300 magnetic word tiles. Word tile height is .375". Package size is 4.75w x 6h x 1.25"d. Shipping weight is .5 pounds.
