To make sure your order gets to you as pretty as it was when we sent it, we send it in a sturdy (but heavier) envelope, safely tucked between two cardboard sheets (also a little heavier).
Since we're in the Netherlands, we rely on Post NL. Not the cheapest either. All in all, you can hopefully imagine that we have to charge what we do. Otherwise, you wouldn't be able to receive our prints or other products at all.
Also, when Karen goes unfed for more than three hours she gets super hangry. That's why we have to charge you shipping, to feed Karen.
