Ordering, delivery and payment
How fast is delivery, and what is the cut-off?
Delivery is free, tracked and dispatched within 1 working day. The line under Add to cart shows today's order cut-off and the usual arrival day. See delivery and returns for the detail.
What's in the box?
What is in the pack is printed on the pack itself. Ask us before you order if you need to know more.
Which payment methods, and why might a card be declined (VPN, 3-D Secure)?
You pay by card on a secure payment page. A card is most often declined when a VPN is switched on, when the bank's 3-D Secure screen is closed before it finishes, or when the bank blocks an unfamiliar merchant. Switch the VPN off, keep the 3-D Secure screen open until it completes, and try again. If it still fails, contact us.
What if a parcel is lost or damaged?
Email us quoting your order reference. Your rights under the Consumer Rights Act 2015 always apply to goods that are faulty, damaged or not as described. See delivery and returns.
Bulk pricing?
For 10 or more pens, or an order over £500, ask for a quote on the contact page.
Is the outer parcel plain?
Yes. Every order ships in a plain outer parcel, with no product names or branding on the outside.
Does each pack have a batch code?
Yes. Every pack carries a batch code. Quote it if you contact us about an order.
