No arrival of order yet, possible shipping issue?

Anyone experience how long it takes for royal mail to deliver to europe, or specific austria? I’ve ordered a blinkstick pro (no tracking standard mail) which got sent off on the 17th of december but have yet to receive it.
It just seems to be a very long time already that I think it has been lost.
Kind of a bummer as I wanted to tinker with it during my vacation time.

I’ve contacted info@blinkstick.com already, but it seems not to be monitored at the moment.

Is there anything I can do?

Hey! Sorry your order has not arrived yet. Will check with Royal Mail tomorrow and will get back to you.

Just a quick update, it has arrived as of today. Thanks for looking into it anyway!
