CustomDUO Shop 


We will be closed 10th July - 11th July 2024

The Online Shop allows payment with most debit and credit cards, without the requirement for a Paypal account. Add product to cart and option is offered at checkout. 


International orders welcome. For more details please see Delivery 


Due to personal commitments, it might take us a few days to post orders until further notice.

(possibly up to 5  days depending on the timing of receipt of your order).

See calendar above. Will try and keep this up to date until normal service is resumed.

Sorry for the inconvenience and thanks for your patience. 


We are shipping to the EU as normal.  We generally post the next working day. However, delivery within the EU is slow at the moment!  Sorry, this is beyond our control, and thanks for your patience. Import charges may apply to orders delivered outside of the UK. 


Please check that your Paypal postal address is correct. We must post to address provided for protection of our customers
