Tri-its are 4 corner, pyramid shaped bean-bags loosely filled with pellets. As the name suggests, tri-its are the perfect prop for 'trying' stuff out. Because of the way they splat on landing they're also perfect for doing neck and foot catches or balancing on your head. Tri-it bean bags are a great introduction to throwing and catching games as well as juggling. We've found that parents appreciate giving youngsters an inexpensive option before investing in some juggling balls. They're also perfect for circus workshops and team building exercises too. The plastic pellet filling means that these are water proof. Price is for one tri-It.
