Twsbi Vac Mini Fountain Pen

The Twsbi Vac Mini is a small, vacuum-filled fountain pen that is known for its reasonable price and build quality.

Usually vacuum-filling pens, like the Pilot Custom 823 are larger, more expensive pens, but that’s not the case with the Vac Mini. This is a small pen that is usually used posted and has a retail price of about $65.

The Vac Mini has a stainless steel nib that is sold in EF, F, M, B, 1.1 mm stub, and 1.5 mm stub. It’s s smaller nib, similar to that found on the Twsbi Eco, not something like the Custom 823 or even the Wing Sung 699.

A typical vacuum design is not suitable for air travel, so the Vac Mini has a built-in shutoff valve to prevent leaks and burps.
