3-in-1 Electronics Cleaning Pen for Earbuds and Keyboards

Three tools in a pen barrel, each for a mess a cloth cannot reach: a pointed tip for the crevice around an earbud mesh, a soft brush for loose dust in a keyboard, and a flocking sponge for the inside of a charging case where lint collects and stops the buds seating.

It cleans dry, so there is no solution to buy, spill or get into something. One dollar, pocket-sized, and reusable indefinitely — the sort of thing that lives in a bag and quietly earns its place.
