Although I didn’t have any issues with customs, I just want to let you know, that I found a yellow sticker on my package that said: “Goods not fulfilling the conditions prescribed by Articles 9 and 10 of the Treaty establishing the European Economic Community”
I’ve no idea what this exactly means and if this will be of significance, but I read in Article 10 that there might be a one year period to get matters sorted. So maybe it might become of significance some time in the future.
