The Research Lab Pen from Kokuyo is a permanent marker specifically designed for writing in critical environments. The oil-based ink is fast-drying, waterproof, and can write on special materials like plastic, glass, metal, fabric, or resin. The ink is alsoethanol-resistant and perfect to be used in laboratory conditions, such as writing on test tubes, vials, or glass bottles. It can even work on surfaces that are frozen or covered with condensed water droplets. The 0.6mm felt tip of this pen also performs outstandingly when you need to write precisely in smaller areas.

Writing performances may vary depending on the surface condition or material. It is recommended to test out the results before use.
