As I'm sure you're aware, Britain is exiting the European Union on the 1st January. We are compliant with the new rules and will continue trading as normal with the EU. Be advised that if you are ordering from the EU you will no longer be liable for VAT, but any duties will apply.



We are still seeing some delays to the Royal Mail and Airmail delivery services with some orders taking much longer than expected to be delivered. If your order is taking longer than usual to arrive, please be patient and bear with us. If you have an urgent requirement, for UK we recommend choosing the Special Delivery option: although next day delivery is not currently guaranteed, your package will still get priority handling and will usually arrive within 1-2 days. For international orders, we suggest choosing the airmail express option at a minimum if you need the goods in a timely manner, and to consider using our courier service (UPS, FedEx or DHL) if it is truly urgent. This is especially relevant if you are ordering outside of Europe.

If you order a custom stencil or custom laser cutting, please make sure to follow the instructions on the product page as closely as possible to avoid additional delays.

We apologise for any frustration this may cause. Stay safe.
