The entire cart uses philips head screws for assembly. It comes with a screwdriver, which is awesome, but it is the cheapest screwdriver available.

Each bin sits cleanly on each other and they look very neat. It frees up space and gives you headache free organization. My only suggestion is they should add a clip to hold the baskets together as one unit.

I like the idea of this however it is very flimsy and not sturdy.
