The Pilot Frixion Ball Knock 0.5 Black – 10 Pen Set provides a practical bundle of erasable gel pens designed for smooth everyday writing. Using Pilot’s unique Frixion ink, these pens let you write, erase with friction, and rewrite as often as needed—all without eraser shavings. With ten identical black pens in one set, you’ll always have a reliable tool ready for notes, study, or office use.
Note: This pen uses erasable Frixion ink. Please refrain from using it for certificates, addresses, or any documents that must remain permanent. Avoid high temperatures (60°C and above) or direct sunlight, as ink may become invisible. Erased text may reappear at low temperatures (around –10°C). For best results, use on standard paper and keep the eraser tip clean.
