Assembly and material:
Völligst quick and easy: unfold, fold down the floor, close zipper on the ground, ready! An Allen key is not necessary)
The material is stable and resilient and there are really nice child-friendly colors. Even more pointed objects / toys could harm the fabric.
Strange odors (ie over flown-away after a few hours) or production error gabs no.
Handling:
The boxes fit perfectly in the shelves of the Expedit series. Since we have this in white, it also looks quite nice in the nursery with colorful boxes in it. They should in my opinion, are in such a shelf, as there is no cover and this may result Verstauberei the content (if only stored and not used).
There are to use in my opinion a small flaw:
If you fill in the boxes kleinteiligeren content - we were Duplo Legos - then "crawl" some parts under the folding floor. However, the need to back out, otherwise the box is no longer true because under the hinged floor is only material and parts rausdrücken located. That is not particularly bad and is, as I said, only in small particle stuff before, but should not go unmentioned.
Should a box once a long time can not require them without problems folded to save space again.
Conclusion:
Beautiful storage boxes, just in conjunction with the Expedit shelves. Especially in children's rooms because of the great bright colors. The material is sufficiently stable. Small drawback due under the hinged bottom "crawling" small parts, otherwise everything ok.
From me for good 4 star.
