- 🧲 Magnet (to remove fallen paper clips inside the case)
- 🔦 Lantern (to illuminate the hole in dimly lit places)
- 🧴 Alcohol wipes (to clean the tray contacts when jammed)
If you use a non-original paperclip, check its diameter: too thick tool can widen the hole, after which the tray will fall out spontaneously. The optimal size is 0.6-0.8 mm. Also avoid using toothpicks or matches: they crumble and can get stuck inside.
