Questions about Toy Box

The boxes are really cool. After 2 years in the children's room, they are all soft. We are switching to a more stable version

What does the bottom of these "3 Sprouts" boxes look like? Any parts that could scratch a wooden floor (e.g. zipper)?

Does anyone know if this toy box fits in the compartments of the Ikea Kallax furniture?

Hello. I would like to buy 3 boxes for the lower price. But do I understand correctly that I will get 3 of the same box? Not 3 different ones?

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?
