### ⭐⭐⭐⭐⭐ Expensive but great pens
*by N***A on 10 June 2026*

The writing experience is amazing

### ⭐⭐⭐⭐⭐ Perfeição
*by J***N on 30 November 2025*

Perfeitos

### ⭐⭐⭐⭐⭐ Escrita macia e não falha
*by R***O on 17 April 2025*

A escrita dessa caneta da Uniball é muito macia. Uma das mais confortáveis que já usei. A ponta é 0.7 mas no papel parece mais grossa do que uma energel. O preto da tinta é forte e não falha. O corpo tem cores sóbrias e o toque parece aveludado, gerando boa aderência da mão durante o uso.
