Thank you for viewing. This item was purchased at an ophthalmologist's office for the care of my child's orthokeratology lenses, but I am selling it because we have stopped using orthokeratology. - Brand: SEED - Product Name: correct clean - Contents: 6 pairs - Purpose: Cleaning solution for hard contact lenses - Expiration Date: ①2026.05 ②2027.06 ③2027.08 This is a cleaning solution for oxygen-permeable hard contact lenses, containing 6 pairs worth of solution, and is a protein cleaning solution for regular, thorough cleaning. In addition, there is one box that expired in 2024.07, separate from these three boxes. If you don't mind, I can include it as a service.
