2 ounces of lens cleaning solution in an easy to carry flat spray bottle (about the size of credit card) along with a microfiber cleaning cloth. A miniature 3-way screwdriver key chain (straight head, phillips head, and tiny nut driver) perfect for replacing nose pads or tightening temple screws. All of which fits into a handy pouch complete with carabiner. The pouch is big enough to add your drivers license, a lighter, maybe even a wad of cash.
