Staedtler Perma Marker – Chisel Tip, Black, Box of 10

Black's the default for a reason. You need it on the cardboard box, the asset tag, the 'DO NOT REMOVE' sticker, the shipping label at 6am when nobody else is awake. Ten chisel-tip markers with ink that dries fast, won't smudge when your hand brushes the package, and won't wash off in a rainstorm. Leave the cap off for days — it still writes. Low odour, so nobody's complaining in the break room. Grab a box before you're down to the last one

• Chisel tip writes 2–5 mm lines — thick for boxes, fine for tags
• Waterproof, smudge-proof ink dries fast on most surfaces
• Stays writeable even left uncapped for days
• Low-odour formula, safe for shared offices and classrooms
• Colour-intense black that reads clearly from across the room
• Box of 10 to keep a spare at every desk or workbench
