Oregistrerad släp med kapell

Max 750 kg Obromsat Sommardäck I gott skick I’ll explain this part in English as my Swedish is not the best.. I recently moved to Sweden from the Netherlands and I had bought the trailer second hand to help move my things. In the Netherlands you can drive a light trailer without registration, you just have to put the plates from your car on it. I didn’t expect the rules here to be different so now I can’t drive the trailer anymore because I’d have to import it into Sweden. Since I don’t really need it anymore, to import it is not worth it and so I hope to sell it. I don’t have any papers for it. Let me know if you have any questions.
