Description
PIGMENT INK ROLLER PEN FOR DOCUMENTARY USE
The O-Write GT5 roller pen is a document-class writing instrument that meets the rigorous ISO 14145-2 standards, which include erasure resistance, water resistance, chemical resistance, light resistance, and bleaching resistance tests (ISO 14145-2 clauses 4.1 to 4.8). Compliance with this ISO standard means that the ORO O-Write GT5 not only fulfills general writing needs but also meets stringent requirements for documentary use (ISO 14145-1).
For writers, this compliance translates to the following:
- Documents written with the ORO O-Write GT5 will remain legible for decades, ensuring timeless records.
- The ink will not fade, even when archived for long periods.
- The writing is tamper-evident, resistant to modifications, washing, or chemical tampering.
