The pen uses standard gel-pen ink formulations that are commonly marketed as non-toxic for everyday writing. Always avoid using near eyes and follow normal safe-use practices for writing instruments.

The 155N in a single-pack format provides straightforward value for everyday writing. When comparing, factor in tip size (0.7 mm here), ink color, and how often you write; it’s often a good balance of cost per pen and writing quality for light to moderate use.

No special installation is required. It’s a ready-to-use gel pen right out of the package. Just remove the cap and start writing.

Store the pen with the cap on when not in use, avoid exposing it to extreme temperatures, and write with a steady hand to prevent ink flooding or skipping. Re-cap after use to preserve ink quality for the next session.

It combines smooth, reliable ink flow with a comfortable grip and quick-drying performance, plus a light sky-blue color that stands out without being overpowering. This makes it a practical choice for notes, documents, presentations, and everyday writing tasks.
