due to changed rules at B-Post (since Brexit), placing new orders with shipping address outside European Union is temporarily disabled (expected 1 or 2 weeks).
I am investigating the options and needed changes to offer shipping outside EU shipping again. If you have urgent orders, please contact me.

Ordering within EU is still possible as usual.
