I bought two of these to match the two Stack ON cabinets I already had. I'm glad they're exactly the same size, so I've lined up four of these for my electronics lab parts now. The plastic boxes on it are made of softer plastic, which I don't really like, but that's no reason to stare as some people might prefer it. They are also not as transparent as the hard plastic used in most partial cases. My biggest complaint is that there are no drawer dividers in the kit, which really pisses me off because now I have to spend another $22 on dividers. Not the expenses I thought I should have paid. If the drawer dividers were included I would give five stars but it seems like it would cost 10 cents to even include them but instead I suggest the seller make a big margin for those of us who have very small parts and who could really use the space if we could separate the drawers. On the other hand, these crates only have a slot to split the crates, so they can only be split in half. The drawers of the My Stack ON 39 drawer cabinet can be divided in half and thirds with two dividers.
