Pentel Oil-based ballpoint pen Vicuna EX2 0.7mm Black

Vicuna is an oil-based ballpoint pen designed to provide a comfortable writing experience.
The unique lubricant that makes the moment you write light is responsible for transporting the ink abundantly to the ball, while the "endless smoothness" comes from the ink viscosity, which is among the lowest in the industry, and the advanced mechanism that controls it.
The colorant used in Vicuna Ink is a dye-pigment type that is a blend of carefully selected pigments and dyes.
The water and light resistance of pigments and the ability of dyes to penetrate into paper provide great color development.
The most commonly used black ink is a deep, pure black with little shine, producing clear handwriting and beautifully finished letters.
