2 sets of 120ml x 2 bottles of oxygen cleaning and storage solution for hard lenses. The one with an expiration date of 2027-11 is unused. The one with an expiration date of 2028-01 has been used only once for one bottle, but the amount of liquid remaining is imperceptible. The other bottle is unused. I am selling these because I switched from contact lenses to glasses and no longer need them. Shipping included, anonymous delivery.
