Cross's masterpiece ballpoint pen, the Aventura AT0152-1 Black. It's a twist-action pen. - Color: Black - Materials: Plastic, Metal - Design: Two-tone body - Clip: Metal clip - Ink: Black Thank you for looking. This is a very orthodox and high-quality ballpoint pen that can be used in any situation. It's believed to be discontinued now. You can buy remaining stock on Amazon, but it costs 5000 yen for a new one. I only used it for a test write after purchase and have kept it stored at home. It has never been taken outside. The twist function works perfectly, and the ink flows. I think there are almost no scratches. If anyone is looking for one, please buy it. Type...Ballpoint pen Ink...Oil-based Body material...Plastic
