Kurutoga Roulette is a solid pencil, but the spinning mechanism feels a bit overhyped, especially with the 0.5 mm lead size. I bought my brother the 0.7 mm version, which works better since it¡¯s less prone to smudging. The handle can also slip, especially for those with sweaty hands, which can be a bit annoying. Overall, a good pencil but not perfect for everyone.
