TWSBI Vac Mini

More than just a smaller version of the Vac 700, the Vac Mini is a more conventionally-styled pen, by TWSBI standards. It's small, but comfortable to use - for a full-length pen, the cap can screw onto the back of the barrel, but it's long enough for most to use unposted, too.

The vacuum filling mechanism makes this the perfect pen for pen geeks, but may seem odd to those without so much interest in fountain pens. It can fill itself very full, especially with the Vac 20A ink bottle, and has an impressive capacity for a small pen, holding much more ink than most full-sized pens can.

The blind cap, when fully screwed down, closes a valve, preventing ink from flowing. This may not seem useful at first, but it keeps the pen sealed so only a small amount could leak out, even if the cap gets knocked off, and reduces the chance of spilling ink into the cap if it's knocked about in your bag or pocket. It should make it safer to fly with, too, though TWSBI don't make any guarantees there. For short notes, you can leave the valve closed, but for anything more, you'll need to unscrew the blind cap, and release the ink - just don't pull it up too far, or you'll make a mess!

  • Bottled Fountain Pen Ink

    Choose bottled fountain pen ink if you want the widest color selection and a more refillable writing experience. Bottled ink works with compatible fountain pens using a converter, piston filling system, or other bottle-fill mechanism.

  • Fountain Pen Ink Cartridges

    Choose ink cartridges if you want a simple, convenient refill option with less setup and easier travel. Cartridges are a good choice for everyday writing, school, work, and anyone who wants a faster refill process.

  • Flushing your fountain pen regularly—

    especially when changing ink colors, every six weeks, or before storing the pen—is essential to prevent ink residue buildup, muddy color mixing, and clogged feeds that can lead to scratchy or inconsistent writing.
