    Solid Shelves
    Style: 36inch 4 tier, Style: 36inch 4 tier
    These are easy to install with the right tools. (STUDS ARE KEY) The only thing to note is, that when assembling the pipes, it takes patience for them to tighten. BUT IT DOES! DONT GIVE UP!!💁‍♀️ They are sturdy, roomy shelves, and very very stylish. The color is very spot on. The shelves in particular, function just as described.
