More info

New for November 2020, the TWSBI Vac 700R IRIS has a titanium finish and every pen is slightly different and unique colour. 

The TWSBI Vac pens have a shut off value internally such that when it is closed there is only sufficient ink for a short passage of writing.  When the filler knob is unscrewed the shut-off valve is opened and the ink reservoir is then connected with the nib assembly and this enables the flow of ink for long writing sessions.  See the instruction manual PDF in the downloads tab a pictorial description.

Overseas shipping starts at only £4.00. The exact cost varies by price, weight and delivery country so to find out your final shipping cost just add the item to your shopping basket and select the delivery country. You don't have to enter any personal details - just an e-mail address but this isn't stored unless you create an account. We offer a choice of shipping services from Royal Mail and DHL.

VAT (at 20%) is automatically taken off for destinations outside the UK. Note that if you are ordering within the EU you will have to pay VAT when your parcel arrives.

If an item is in stock, the words "In stock" will be shown. If an item is out of stock, the approximate number of days before we get another delivery will be shown instead. You may still be able to order the item, but there will be a delay before we can dispatch your item(s). If the words "Please enquire" are shown, it's best to check with us first before ordering.

Nib choices for fountain pens
If we show the pen with the default nib selection shown in stock it means we have stock of that pen. If you select another nib size and the website doesn't say "in stock" we can usually supply that pen immediately as we keep extensive supplies of nibs from all our manufacturers.
