Gift Wrap
We offer a professional giftwrap service to complement your pen or leather journal. Simply check the giftwrap option on the product page before you add to basket (a charge of £3.25 will be added).
We use a premium silver giftwrap paper with a subtle two-tone patterned effect, and a hand tied silver ribbon. We also include a matching gift tag, which can be appended with a message of your choice. Simply add your message to the text box when you reach your basket. Items are giftwrapped individually i.e. if you order several items only the specific item requested will be wrapped.
We do not include any paperwork inside the giftwrapped item. If you select a different delivery name to your billing details, we add a gift receipt which hides all prices.
Nib size guide
- Smooth steady ink flow
- Distinct line variances
- EF particularly fine
Easy filling on-the-go. Ideal for popping in your bag or laptop case, this little fountain pen extends to full length when the cap is posted. The inbuilt vacuum mechanism fills the barrel with a simple up and down of the plunger and helps prevent leakages by creating an internal seal when fully screwed in. Whilst writing, unscrew the mechanism tip to break the seal and allow the ink to flow more freely. The VAC’s demonstrator style transparent body lets you to see the distinctive mechanism within and remaining ink levels, whilst the screw close cap and rubber O-ring create another seal to further stop leakages or drying.
All TWSBI fountain pens can be disassembled for cleaning and maintenance. TWSBI includes the tools to do so, but recommend this is only carried out by experienced fountain pen users. This should only be carried out as part of long term servicing of the pen; it will not need to be done straight away. All disassembly is carried out at the owners risk!

Probably the best TWSBI fountain pen, and I have a few.
The size and the balance is perfect for me, despite having large hands. The ink flow is perfect, rather wet and can be used with "dry" inks. I am not into transparent and demonstrator pens, but this is a beautiful writing tool, a pleasure to look at.
The package arrived in 2 days - as usual - excellent service.

Absolutely comfortable to hold. Writes very well and holds so much ink (about 2.5ml).

TWSBI was named for the Chinese phrase “San Wen Tong” (Hall of Three Cultures). These initials were reversed (TWS) and "Bi" added (literally meaning writing instrument) to create the TWSBI name
