Very comfortable to write with! My mother has essential tremor in her hands (mild to moderate), and she found that the weight and shape of these really helped her write more clearly. I got one .7 and one .5 mm to use for myself, but ended up passing the .7 onto her- she found the .7 easier to write with at various slanted vs. upright angles, whereas the .5 requires more precision. The pen writes very smoothly, and it has excellent weight and shape. Recommend!
