Heads up, going to be juggling balls for a most of September due to unavoidable life committments !! .... so apologies in advance for any disruption to normal service (i.e. responding to emails, posting stuff out, etc etc)

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. Please note, the postage rate has been set to accommodate international orders. UK postage costs less.

Please feel free to Contact Us for a reduced UK postage rate. Payment by bank transfer required.
