Review: Do not get if you like smooth inks - Bought this pen to try Jetstream ink and, I don't like it. I think if you like smooth inks like the Acroball ink, you won't like it. Other than that, Pros: -Fast-drying -Cheap, premium looking barrel Cons: - The feel of the jetstream ink feels too coarse for my liking - The plastic feels really cheap

### ⭐⭐⭐ Esperaba más!
*by E***E on 13 February 2024*

La verdad no me gusto tanto. El color está súper brillante. Y funciona como un bolígrafo normal, no corre bonito el trazo, lástima por que ahora hasta los repuestos son caros
