Category Tips
- Sharpening Care: Use a high-quality, sharp blade sharpener to accommodate the wider 4.0mm soft lead core safely without binding.
- Stain Prevention: Keep tips capped or stored face-up in pencil holders because the rich, non-erasable blue pigment can mark fabrics if rubbed aggressively.
