Key features

One push, one clean: press the pen in until it clicks — the tip rotates a half turn while a fresh length of densely woven microfiber thread sweeps the end face, lifting dust, oil and debris without scratching it
800+ cleans per pen: the thread advances automatically with every push, so clean number 800 is wiped with unused thread, exactly like clean number one
Dry cleaning — no alcohol to carry, spill or wait on, and no solvent residue left on the end face
Cleans connectors where they live: through the adapter on the panel, and unmated connectors in the hand; SC, FC and ST, UPC and APC polish
A window on the body shows the thread remaining, so the pen never runs out mid-job without warning
