Each 20" rack is crafted from thick, luxe acrylic for a sturdy, high-end feel. We've added a scalloped pusher, plus strong magnets to hold your pusher securely in place while playing and when storing. The extra length gives you room for you to build your walls with all 160 tiles (if you play with all 10 Jokers and 6 Blanks - we see you!) Even playing with large format tiles like ours, you won't have any tiles in your wall hanging over the edge of your rack. Set includes 4 clear acrylic racks with matching scalloped pushers. 20" long x 2.6" deep
