Mechanical Eraser Pen Refill, Set of 2 Leads

Replacement eraser sticks are the consumable half of a click eraser pen. The pen body will outlast a great many of them, so once you own the pen the only thing you ever buy again is refills.

Check the diameter against your pen before buying: eraser refills are not universal, and a stick even slightly undersized will slide back into the barrel every time you press it against the paper — which feels like a broken pen but is only the wrong refill. Keep a pack in the drawer rather than discovering the pen is empty in the middle of a drawing.

Two replacement erasers supplied as leads. The word lead here means the stick format rather than the material — there is no graphite in them; they load into the barrel the same way a clutch pencil lead does, which is where the name comes from.

• Set of 2 replacement eraser sticks
• Check the diameter matches your pen
• A consumable — keep a spare pack
