Get that last drop of ink out of your ink bottle or ink well with this ingenious device. Simply plug it into the end of your converter (see below for compatibility) or TWSBI Diamond series barrel and use it to draw up ink when the level in the bottle is too low to immerse a pen nib.

To use with a TWSBI Diamond series pen (TWSBI Diamond 580 and TWSBI Diamond mini models), remove the nib unit first by unscrewing from the barrel. Replace after filling (do not over-tighten).

Compatible with standard-size ("international") converters, such as Waterman, Visconti, Faber-Castell, Montegrappa, Edison, Esterbrook, Schimdt, TWSBI etc.

Note that this device will not work with Parker, Lamy, Aurora, Cross, Sailor, Pilot, Namiki or Platinum converters.

Shipping cost and availability

Shipping cost
UK postage is FREE over £35 but otherwise starts at £1.80 for small items (converters, refills etc) or £3.30 for ink, stationery etc.

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.
