TWSBI Vac Mini Fountain Pen


What do you think about TWSBI’s policy of launching new pens into the market and updating the ones already launched? For me it is superb! Because I was in love with Vac 700 while it is too big for my hands. Vac mini grants me the opportunity to have a mini pen with great ink capacity.

Vac Mini comes in classic white plain box of TWSBI pens. The box contains gadgets to disassemble the pen and a mini silicon gres.  For me I never ever disassemble a TWSBI of mine. I didn’t need it at all…

Vac Mini is really a tiny pen however you could easily forget this with its 2 ml ink capacity. Especially when considering a standard converter only holds 0.75 ml of ink, 2 ml will be enough for a really long time.


TWSBI Vac Mini is a pretty pen. I like seeing the inks through. My version of this pen is called Smoke. The grip section and the piston knob is a transparent black in this pen. In the clear version these parts are all crystal clear. And if you are not happy with the size, you can screw the cap on top.   

My pen has a Fine nib. It is quite suitable for daily use. With high ink capacity and clear body allowing you to see through how much ink left so that you will never left out of ink in a sudden, TWSBI Vac Mini becomes a great daily pen. Tuck it in your pocket and go out!

And how does it write? This fine nib is one of the best fine nibs I have tried recently. Especially they became a great pair with Pelikan Edelstein Jade so that I had hard times returning it to Mr. KGK.

What is your mini-giant pens?

  1. So happy to read your review! I am looking at TWSBI Mini for the size and piston fill. At first I thought it was too small for my hand, but it is similar to my Pilot Prera which I really enjoy. I tried the 580, and returned to the more comfortable Mini.

    This Mini you show has a F nib but made by the German JoWo. I am used to the Japanese F nib (it is so excellent for writing Chinese and Japanese…obviously!), so I think an EF will be better because it will be closer to a Japanese Fine nib. It’s all about the nib, right?

    Both the Prera and the Mini I can use daily, and they can live a harder life than, say, my Pelikan 400 tortoise. That pen has an okay design (well, a bit boring really), but the body is delicate, and the nibs flow with too much ink. I hope to find a buyer who likes it. Then I can be happy with a new TWSBI Mini.

    • Thank you Bebe!
      For me, the colors of Pelikan 400 tortoise is too bright. Although I have one, I seldom use it. I think I like vintage tortoise best! It is darker and more pleasing in design.

  2. Hello Zeynep,

    Thank you so much for the review. I am the happy owner of a few Twsbi pens, but I never purchased the Vac Mini, probably because I keep buying vintage pens at an alarming rate, but I digress… Your post rekindled my interest in the Vac Mini as a near ideal pocket pen; from what I could gather online, it is a bit longer than the normal, piston Mini (which I own, fitted with a F nib ) which I found to be really shorty, so the Vac Mini must be very close to what I am looking for. Besides, the ink capacity is also larger, so we are talking about a win-win situation.

    Another advantage is the fact that the Vac Mini has the same nib shape and size as the TWSBI Mini and TWSBI Eco, so one can swap nib units between all the three models without any hassles.

    As for the ability to disassemble Twsbi pens, I see it as a great plus: recently, I had to take my Eco apart to clean it after using a high density, heavily saturated ink. I wish I could do this as easily with other, much more expensive pens…
    Best regards,
