There's a raised lip on the finished side of the space, and just be sure the round cylinder stays "seated" in the circle.~~ starting with the top piece laid upside down, be sure when adding the additional glass shelves that the bottom of the shelf is facing up

You get 5 glass shelves, 8 cheap pieces of threaded rod not even full length section to save shipping costs, a bunch of pieces of electrical conduit cut up and painted black, had to remove some burrs off mine they missed at the factory, and a bunch of low quality plastic spacers that will leave you with nothing once they breakdown, wouldn’t leave it anywhere the suns rays strike it

~~ you start with the top piece laying upside down on the floor

Very nice accent piece, which is sturdy and easy to assemble.

One piece came broken but super glue did the trick since did not want to go through any hassle looks nice in game room
