Wonderful pen!
I am very happy with this pen. I’ve been using it to creat zentangle designs and it does a great job on the tiles. This has become my Go To pen for sure!

Best pen in the whole world. Period.
I've been using this pen every day at work for more than 10 years. When I moved to the US I couldn't find these so every time I went back to Portugal I would get a refill of Uni Ball pens. Until the day I find out that they were available at Amazon! Trust me, this is by far the best pen you can find.

10 in a box marked 12
Only 10 not a dozen in an open box...almost like someone needed a pen and said...hold on I’ll get one out of this box. So I was shorted when shipped. I’ve no time to return it so I’ll just write about it here.

Super Stifte für Korrektuen
Die besten Korrekturstifte, die ich seit Jahren gefunden haben. Halten lange, verwischen nicht und sind Dokumentenecht. Kaufe ich wieder

La qualité est au rendez-vous
J'utilise principalement ce pencil pour corriger les travaux de mes étudiants. Le trait est fin et permet aisément d'annoter entre les lignes. L'encre ne coule pas et sèche très rapidement. La pigmentation du rouge est dense. Parfait !

De calidad
Es un producto muy bueno, los uso muchísimo. Puedes ver en todo momento la tinta que queda porque tiene una zona que la deja ver. Dos pegas: 1- Cuando junto dos páginas enfrentándose una a otra, se manchan aunque la tinta ya se haya secado. 2- La calidad precio no es muy buena, me parece un poco caro este pack.

Great rollerball
My favourite roller ball with fine line width and lack of smudging.
