Each ink cartridge used in the BHK-40-D 4-Colour Recycled Ball Pen Range is fully compliant with ISO 12757-2, the internationally recognised standard for writing instruments intended for documentary use.
This ensures suitability for official records, administrative documentation, and materials subject to retention, audit, or regulatory review. The inks have been tested by international independent testing laboratories, providing objective verification of performance and compliance.
Key ink performance attributes include:
- Consistent ink flow across all four colours
- Clear, legible writing on standard office paper
- Resistance to smudging under normal handling conditions
Independent laboratory testing supports procurement teams in meeting specification requirements commonly referenced in ITTs and RFQs, reducing risk during evaluation and audit processes.
