KOKUYO Research Lab Pen — 0.6mm, Black

The KOKUYO Research Lab Pen is perfect for labeling in a lab or everyday use. Its oil-based ink sticks to almost any surface and resists water and alcohol. It can even write on wet or frozen surfaces. The 0.6 mm tip is fine enough for small labels but bold enough to read from a distance. The pen has a sturdy metal barrel and a fluted cap that’s easy to remove, even with gloves on.

Notes:

Store the pen horizontally when not in use to prevent drying out.

Ink may not survive autoclaving—test before use.

Performance may vary depending on surface type and condition.

Not suitable for underwater writing.
