These visuals are great for Special Education teachers. They are especially helpful for students with autism. Made from vinyl that sticks to a door. *note that they will stick to a glossy finish paint(found in most classrooms) but they do not stick well a matte finish.
They measure 6 inches by 5 inches. I can print them in almost any color. They come in sets of 5. You pick how many "stop" hands and how many "wait" hands you want in your set. I also sell them individually, just check out my other listings or email me.
