Antibacterial cleaning solution for hard contact lenses, providing approximately 3 months of use with thorough cleaning. This is being sold because I switched to soft contacts and no longer need it. It's new and unused, with the box unopened and stored in a dark closet. I'm also considering selling individual bottles. Please consult with me.
