Marker for deep holes Pica-Dry®
Execution: Replaceable graphite cartridge. The automatic feed mechanism of the cartridge located in the stainless steel tube prevents the cartridge from falling out, with a handy case with a special hook that allows easy one-handed pulling, with an integrated cartridge sharpener.
Use: For writing and marking on almost all material surfaces – it doesn't matter if they are dry or damp, smooth or rough, dusty or oil-stained.
