Review on 🌀 ELUTENG 120mm Fan Filter 2 Pack: IP40 Dustproof Blower Guard for Case Fans - Tool-Free Mesh Cover for Effective Ventilation and Dust Prevention by Kyle Hoes

I find it very strange that they come with a screwdriver but no screws. Kind of a head scratcher. Neither is a flathead screwdriver, I don't think I've ever seen a "fan" pan head screw, especially one so small that a screwdriver would be useful. Just weird. Otherwise quite acceptable, not expected but I really like the dual layer design, the filter fits between two frames, works really well once you find some screws!
