Acro Ink is an oil-based ink that is very popular for its smooth writing feel. Why not take a commercially available high-performance ballpoint pen and transform it into your own unique pen, incorporating the gentle, luxurious feel of a wooden pen? The finish involves 8 stages of polishing and is coated with a penetrating inorganic glass coating. The glass coating thoroughly protects the wood from dirt and moisture, providing a long-lasting effect. While possessing very strong water and stain resistance, it does not create a film on the surface due to its penetrating nature. After complete drying, the natural feel of the wood remains intact, and you can still enjoy the scent of the wood. By preserving the natural beauty of the wood and using it properly, you can enjoy it for a long time with no maintenance required. The finger contact area is shaped with a constriction, carefully crafted to be easy to grip and prevent hand fatigue. The original pen tip is also a metal die-cast product. It has a low center of gravity, making it very easy to write with. Notes: As this is a handmade product, please consider carefully before purchasing if you are looking for a perfect item. Maintenance only requires a gentle wipe with a soft cloth.
