I offer these wheels in 2 sizes:  30” diameter and 24” diameter. They attach to your wall with 2 screws that fit into inset keyhole fasteners on the “gooseneck” back.  Unlike a painting however, these wheels spin like a “wheel of fortune.”  They are great to have in your game room, bar, living room or any other place in your house where you’d like conversation and excitement to abound. Have fun!
