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.
