This oil-based pen features highly alcohol-resistant ink, ensuring that writing remains clear even if alcohol contacts the writing surface. 

With a fine, durable tip crafted from a hard material, it produces precise lines (approx. 0.6mm) and uses quick-drying, smear-resistant ink, making it perfect for small surfaces like microtube lids. 

The specialized ink also enables smooth writing on frosted or condensation-covered surfaces, making this pen ideal for marking lab equipment such as tubes and

 petri dishes.

Although it uses ink that does not easily mix with water, it cannot be written in areas with large amounts of water or underwater.
●Can be used on paper, cloth, vinyl, etc., but writing performance will vary depending on the material and surface condition.
