Review on 🔧 Eyeglass Repair Kit with PTSLKHN Sunglasses Repair Equipment - Includes Air Chamber Eyeglass Nose Pads, Screws, 3 in 1 Micro Screwdriver, and Precision Screwdriver Set for Eyeglass, Sunglass, and Watch Repair... by Diana Johnson

This is a good deal for the money; and a life saver if you lose two (or even more - just one) nose pads. The instructions contain information on the common sizes of various spare parts for glasses. I haven't used it to fix clocks, but I think it might be useful. The manufacturer's description I read said a magnet was included. If it's not the metal strip on the back of the screwdriver set, it hasn't been installed. A more important downside is that the container that stores all the screws isn't intuitive to use. It spins; and only closes at the top or bottom, but not on both sides. Note the white triangular cover on one of the holes; and slowly turn it until it is to the right of the desired screw size. This will ensure all other sizes don't fall out when you invert the container to get the correct size.
