Getting a Full Fill on a TWSBI VAC-700

The TWSBI VAC-700 is a pretty cool pen, check out my full review of it here. It has a pretty interesting vacuum-filling mechanism, not all that common in pens today. Doing a ‘conventional’ fill, you get about 1.5ml of ink in it, which isn’t shabby at all (about 3x’s the capacity of a standard cartridge/converter). However, if you’re like me and you derive a sense of personal satisfaction from maxing out your pen’s ink holding capabilities, you can get a full 2.3ml into your VAC-700.

This technique can be used for any vacuum-filling pen such as the Pilot Custom 823, as well. It does take a bit of practice and some guts to take the risk of shooting ink everywhere, but if you’re like me and live life on the edge (not really), you’ll enjoy having one of the largest ink capacities around. Let me know what you think!

    Thanks for the technique of completely filling the Vac 700, Brian, but a regular fill would do it for me.  The regular fill is still going to give me a heck of a lot of writing without the risk of ink everywhere.

    On a side note, your walls and desk are bare.  Boring!  Where are all of those letters and drawings you get from all of the Goulet Pen Company devoted fans? 😉  And is that a Joseph masterpiece on the wall behind you?

    I use the same technic with the 540 to entirely fill it, just using the piston.

    What's life without a little (inky) risk? 🙂 I also do the same thing with my converters when I want to top it off with more ink. 

    Also, what music are you playing in the intro? I love it!

  • Indeed! haha, the music I use is just stock music from iMovie 🙂 

  • Yup! The idea behind getting a full fill is the same on every pen….expel the air, replace it with ink 😉 The technique might be a little different pen to pen, and one like this is easiest to show in a video.

  • I did this video just so you could have the option, it's totally fine if the 'risk' isn't worth it! 1.5ml is a plenty generous fill. 

    My walls are bare, I know! We have all the letters from the 'old' shop and we're waiting to put them up. I think on the walls of my studio are a definite contender….it just takes a lot of time to put them up and I haven't had the time. Yes, that is a Joseph masterpiece, it was some artwork he did for me for my birthday 🙂

    Does the method place undue stress on the seal at the back (top) of the pen? I am thinking specifically of the point at which you have a pen full of ink and then pull the plunger back prior to expelling air for the second fill.

  • Honestly, I don't know. I don't suspect so, because the amount of pressure required doesn't feel any greater than when you're filling normally. But if it worries you, just do a normal fill and don't worry about the extra ink, 1.5ml is plenty anyway, really!
