Y.R.U Hologram Light Up Sneakers

Y.R.U Hologram Light Up Sneakers that have only been worn twice (to work and one day at a theme park). Shoes still light up, however, the clear plastic casing for the lights have yellowed despite being stored in a closet and in their original box. Colors are still quite vibrant and no evidence of yellowing when lit up. Other than the yellowing, shoes are in near mint condition. Size USA 11
