## Shipping policy

All products purchased from this store ship directly from me here in Melbourne, Australia.
Orders are processed daily and usually go out within a few days!
I'm currently unable to ship to Germany, Denmark, or Sweden, but I am doing my best to work with Australia Post and Zonos about this issue; sorry for any inconvenience.
Finally, postage rates suck, and they keep going up; sorry :(
