RHODIA SCRIPT 0.5mm limited edition turquoise. It has a hairline finish and a hexagonal shape, making it easy to hold. It's also slightly shorter than a regular mechanical pencil, making it easy to handle. I've been a mechanical pencil enthusiast, but I think this is the only one that has such a luxurious feel and is so comfortable to use. There is no distortion in the tip. Also, the pen tip can be stored, which is convenient. Please refer to the images for details on the condition.
