## Questions & Answers

**Q: Does this pen use the Diamond 50 Ink Bottle?**
A: Sorry, I refill my Twisbi from a regular Noodlers Ink bottle.  I suggest you contact Twisbi for a definitive answer.

**Q: How is this pen for getting used to if you are new to writing with a FP?**
A: The TWSBI ECO is a great pen.  I use it for drawing as well as writing.  The pen is a joy to use and you should have no difficulty with it.

**Q: Is it worth buying this pen? Should I wait and save money for a different pen or is this pen worth the price for how it writes**
A: You should definitely buy this pen.  It writes beautifully.  I am very satisfied with my purchase and this is one of my favorite pens that I write with.

**Q: does it need an ink cartridge?**
A: It cannot use an ink cartridge. You must have a bottle of ink. 

It is what's called a piston filler. You draw ink up into the pen barrel from a bottle of ink. 

For some ink brands on Amazon, check out Noodler's Inks and Diamine inks. 

Hope that helps!

### ⭐⭐⭐⭐⭐ Review
*by G***I on 21 December 2020*

Conoscevo il marchio ma non avevo ancora posseduto una delle loro penne, beh devo dire che è una bella penna; non è piccola e nonostante il materiale sia prevalentemente plastica, non è neanche troppo leggera, ha la giusta consistenza. Il pennino "M" scorre molto bene ed ha un flusso anche troppo abbondante, scrive sempre. Speriamo che sia un prodotto durevole nel tempo, visto l'abbondanza della plastica. Al momento soddisfatto dell'acquisto. Il venditore è stato molto puntuale ed il materiale è arrivato adeguatamente imballato, ottimo acquisto.
