Shipping cost and availability

Shipping cost
Overseas shipping starts at only £2.50. 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.

UK postage is FREE over £20 but otherwise starts at £1.50 for small items (converters, refills etc) or £2.95 for ink, stationery etc.

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).

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.
