Hopefully this will help those who still have questions:
To check your shirt's shipping status, go to the mu-mo Order Status page.:
https://shop.mu-mo.net/avx/sv/mypord...teg_id=8002136 You will need your order number (in your confirmation email from mu-mo) and your tenso phone number (found on your tenso profile) to check.
Tenso is only responsible for getting the package from their office to your mailbox, so they will have no information about shipping until after they have received a package from mu-mo.
