TWSBI Precision Fountain Pen - Gunmetal

I enjoy this pen. I have the EF, which writes smoothly with an impressive capacity. It's also very robust which I appreciate. However buyers should be aware of the two rubber o-rings at the bottom of the pen that are part of the capping mechanism. They work well and securely hold the cap - until they break off. Mine did so recently, and given they are on the outside of the pen they're easily damaged. TWSBI's service is good; they seem well aware of the issue and will replace them - for $9 US. The single flaw in an otherwise excellent pen.

The smoothest writing pen i have. Matched with some noodlers eel series inks, and words almost write themselves. it was a big chunk of change but i don't regret getting this pen. you won't either.

I have looked at this pen since I got into fountain pens a couple of years ago. I don't know what took me so long, but I am glad I bought it. Shockingly light pen for a metal body. I have had no problems with mine at all. The facets line up body to cap on mine if I don't over tighten it. This will be my EDC pen until it goes or I do!!!!! Beautiful high quality pen, worth every penny...

This pen was given to me as a gift, and it is beautiful! I've read about some people being concerned about weight, but it feels great in hand. It posts perfectly, writes smoothly without skips or stops, it looks really professional but cool, industrial yet elegant. It's my favourite pen by far! Beyond that, Wonderpens is a great vendor and makes buying too easy and enjoyable!
