Norway: Priority

Priority labels from Norway. These are from 'Bring', which is a part of the Norwegian postal service. They were established in 2005 for companies I think. But I haven't seen these labels until recently, like in the last 5 years or something. I'm pretty sure everyone can use 'Bring' now, not only companies. 

If anyone has a year when these labels came on the market, let me know.

They are from a roll of 500.
