鋼針

Finally a needle thin enough to clear the wax out of my IEM nozzles without scratching anything. The steel tip is rigid but doesn't bend like the flimsy plastic ones I've used before. Small thing, but it lives in my case now.

Didn't expect much from a maintenance tool but this needle fits perfectly into the mesh filter on my in-ears. Clears out earwax buildup in seconds without bending or scratching anything.

Wasn't sure a single needle was worth it until I used it to clear wax from the tiny mesh on my in-ears. The tip is thin enough to get into the nozzle without bending, and it's stiff enough that I'm not worried about it snapping off in there.
