Uni-Ball Ub155 Micro Deluxe Rollerball Pen Ultra Fine 0.5mm Tip 0.2mm Line Blue Ref Ub155Blu [Pack Of 12]

Good pen

Bolígrafo de 0.5 mm estupendo para realizar bocetos u obras sobre las que trabajar luego con acuarela (para eso lo compré) porque resiste al agua y no se corre la tinta. En cuestión de un minuto ya puede mojarse sin problemas. Buen diseño y encantado con él.

Great pens

Absolutely love this; ideal for my collection; it is micro tip but not scratchy

اشتريتها بداية العام للأبناء وهذا النوع غير دارج في المحلات ونوعها ممتاز وسريع الكتابة

Other reviews have said it all, really, these are lovely and the ink composition is perfect - gives a good strong black colour, fine and delicate lines good for small detailed notes and diagrams, perfect weight, totally indestructible. I wrote out some script with this and with a Pilot Metropolitan fountain pen and both looked absolutely identical to the eye, they're very similar to black fountain pen writing - the only difference is, this never leaks or dries up. Most importantly, the ink dries really quickly, so if you're left-handed like me, the heel of your hand won't smear the preceding text. These are the only pens I've found that don't smudge at all for me, even writing very fast.
