Ophtecs Hydro One Step 360ml is a convenient contact lens cleaning solution that comes with 5 storage cases. I switched to daily contact lenses, so I have this left over and unused. It has not been opened, and I have extra cases, so I can include them if you wish. *Expiration date is May 2026. I will dispose of it after the expiration date. - Brand: Ophtecs - Product Name: Hydro One Step - Volume: 360ml - Accessories: Storage cases (5) Thank you for looking.
