Thank you for viewing. This item was purchased at an ophthalmologist's recommendation for my child's orthokeratology care, but I am selling it because we have stopped using orthokeratology. *I am also selling other care products, so combined purchases are possible.

I am selling a set of 3 boxes. - Brand: TORAY - Product Name: Gan Jun - Volume: 12mL - Purpose: Insertion solution specifically for hard contact lenses - Expiration Date: September 2027
