Menicon Lens Case for Hard Lenses (Instructions) Fill the lens case with the designated solution up to 90%. Completely submerge the lenses. Rinse the inside of the lens case with tap water and allow it to air dry after each use. The contents have been checked after opening the box. The front plastic wrap has some wrinkles, so it's offered at a lower price. If you are looking for one with no wrinkles on the unopened plastic wrap, I also have a set of three available, so please take a look. Thank you for understanding that this item has been handled by a person. Simple packaging.
