This set is awesome. I have a million pairs of readers everywhere in my house. Sunglasses are abundant too. I am forever losing a screw in one pair and borrowing from another. This kit comes with all sizes and lots of them. The screwdriver that comes on a keychain, has a phillips and a regular head and has an end that holds the nuts in place to tighten them. There is also a set of tweezers to pick up the tiny screws. Great set.
