I have three concerns with that box. The first is the same as the previous concern which is that there are a lot of slots and edges that a baby could get stuck or rub an edge the wrong way. The second is that I have had plenty of clutches where 2 or more eggs stuck together in a way that I was not inclined to force them to separate. In that case, the eggs might not fit. The third is whether or not the box is air tight to keep your humidity right. I guess you could add a layer of press and seal between the lid and box but not clear if there is enough clearance from the eggs to do that.
I have always used a 6 qt sterilite, 2 inches of perlite with water to 1.5 inches, a piece of light diffuser to separate the eggs from the perlite, and a piece of press and seal between the tub and lid. All proven, cheap, and reliable.
