Very nice. Each unit even came with a polishing rag. No instructions in the box but it's quite straight forward, just a lot of nuts/bolts to screw-in (20 sets). It took 10-20 min to assemble each stand. I got 2 stands and they both had extra nuts/bolts (6 in one, 2 in the other). I didn't lose any, but it was good to know they were there if needed. I'm using them for craft/paint shelving, not nail polish. Each shelf has a front and a back wall to hold the bottles (up to 37mm or 1-7/16"). My bottles were too big, but I was able to install the shelves upside-down with no issues. This gave me larger shelves (43mm or 1-11/16") that were a perfect fit for my bottles. I should be able to place 35 bottles on each stand. A great way to get organized!

simple assembly even if there is not instructions.

Lokks and works as advertised
