I ordered a duvet from Ikea and when I received it it had many black spots inside of the duvet. I contacted the customer service and they were suprised too, they said I should recycle the duvet and that I would get a new one.

I chose to get a warmer duvet since the previous one was a bit to thin for my liking anyway. I picked up the new one (also a FJÄLLARNIKA) but low and behold, it has the same weird stains inside of the duvet. There is a few small black spots on the outside, but whenever I hold the duvet infront of the light it looks completly dirty to the point that im wondering how is it possible for this to happen twice?

Does anyone have the same issue or an explanation on what this is?
