Sandy Insert 12 inch Size

If you already own a Wodent Wheel a 12 inch size (measure across the front of your wheel before ordering) it should measure 12 inches across to use this size Sandy track, and you wish to purchase just the running track to insert into the wheel we offer... The Sandy Wheel Insert™. You just pop off the outer cover of your Wodent Wheel, remove the regular running surface, then pop-in the Sandy Wheel Insert. Leave the Sandy wheel in your pets cage for 24-36 hours. When you are ready to switch back to the regular wheel, just reverse the process! Sandy Insets are washable, and typically last 6 months or longer before they need changing. Make sure to measure before ordering! Remember Sandy Inserts come in 3 different sizes, for the 3 different size Wodent wheels - 8 inch, 11 inch & 12 inch (size is determined by measuring across the front of wheel).
