Mitsubishi Uni-Ball One Gel Ballpoint Pen Refill, 0.38mm, Black, 10 Pack

The Mitsubishi Pencil Gel Ballpoint Pen Refill, Uni-Ball One, 0.38 one, Black, 10 Leads features new technology bead pack pigments that produce darker text, making it a memorable writing experience. Developed in collaboration with Ritsaikan University, the black ink is proven to be darker and crisper than general gel inks, leaving a lasting impression on the user.

The "Uni-Ball One Ink" formula has been specifically engineered to optimize the ratio of solids and liquids, allowing the liquid ingredients to be quickly absorbed into the paper surface while leaving a solid color material behind. This results in a quick-drying, non-smearing ink that does not bleed through the paper.

The product line-up includes a 0.38mm version in three vibrant colors – orange, baby pink, and yellow – as well as a 0.5mm version in orange and yellow. For those interested in memory and memorization exercises, the 0.38mm version also comes with a red sheet.

Key features of the Uni-Ball One pen include:

1. Darker black ink and more vibrant colors, making the writing crisp and easy to remember.
2. Non-smearing, quick-drying ink that penetrates the paper surface without bleeding through.
3. Available in 0.38mm and 0.5mm sizes, with the 0.38mm offering a selection of three colors and a red sheet for memory exercises.

The pen's dimensions are 6.0 x 6.0 x 112.0 mm (Shaft Diameter x Thickness x Total Length), and it weighs 42 g. It is compatible with the UMN-S-38 (uni-ball one 0.01 inch (0.38 mm)) model.

By adjusting the language structure and emphasizing the key features, the Uni-Ball One pen's benefits are presented in a more organized and engaging manner, enhancing the overall reading experience.
