Long lasting and quality.
Great deal for a multitasking of these pens. They last for ages and don't tend to clog up as easily as other liquid ink pens. I am looking forward to purchasing more of these in the future but I am yet to run out after a year!

The Best of the Best.
The only pens I write with given the choice. Incredible depth of color, great for visibility. The "Micro" variety are the perfect balance between smoothness and scratchiness when writing. This box is the best value per unit I've been able to find, and they last a good amount of time given the strong flow of ink.

Good if you like a fine line
Quite scratchy so depends on your hand writing style - mine can be a little messy so these are handy for me actually. Ink is pretty free flowing but if you had a heavier hand then could be a bit 'scratchy' I'd imagine.

I just love these pens
These are by far my favourite pens in this price range, personally I think they're better than many of the parker pens. They wrote smooth and consistent, have never had an ink clog, ink doesn't fade much, if at all, even after a few years - I still have notes from years ago with this ink that are as black as new notes. Only downside to these pens is they can smudge when fresh, and one that doesn't affect me, bleed through pages if the GSM is less than 80. Strongly suggest getting a high gsm note book if you intend to use these, I use 100, and 120gsm for writing.

Best of the best
Loved my last one so much, I decided to just buy a box full. Quality is top and they last an age. Sure, we don't handwrite as much as we used to, but I still prefer pen and paper for note taking. The micro tip is just perfect and writing feels natural and seamless. Could not recommend them more.

Ho provato molte penne, ma come queste nessun’altra! Ho già usato due pacchi da 12 penne e ne acquisterò altri. Hanno un tratto continuo e uniforme, sono molto scorrevoli e alleviano la pesantezza della scrittura anche dopo ore di appunti. Degno di nota l’inchiostro impermeabile e che non sbiadisce nel tempo, è un grande pro se si devono compilare documenti importanti o nel caso in cui un quaderno con importanti appunto si bagni. Ho avuto modo di testare l’impermeabilità dell’inchiostro lasciando in ammollo un foglio scritto con queste penne, le scritte non hanno subito alcun danno, assolutamente nulla. L’impugnatura non ha nulla di speciale, è ben dimensionata nella circonferenza, ma questo è soggettivo e pur essendo liscia non la trovo scivolosa. Durano abbastanza, forse un filo meno di una comune Bic, ma comunque soddisfacente. La forma della punta a cuspide sottile permette di avere un ottima visuale di dove si sta scrivendo. Il prezzo unitario nel pacco da 12 a mio parere è corretto. Passiamo alle note negative (poche). Non le consiglierei ad un mancino, perché non sono rapidissime ad asciugare e passandoci sopra con la mano si rischia di sbavare, io sono destro e non ho avuto problemi di sbavature con queste penne. Purtroppo alcune penne (più o meno 1 o 2 su 10) smettono di funzionare a circa metà carica non mi è chiaro perché. In generale posso dire che reggono e a volte superano le prestazioni di penne molto più blasonate e decine di volte più costose.
