Question about 3 Sprouts Toy Box

Hello everyone, we bought two of these visually very appealing and robust toy boxes (owl and unicorn :)) and our little one was very happy about the beautiful motifs. But unfortunately, even after several months in a well-ventilated children's room, both boxes still smell very strong and so do all the toys we store in them. I can only describe the smell with difficulty (like wet cardboard perhaps?) and an enquiry with the manufacturer has so far remained unanswered. Is this also the case with your boxes?
