Gorgeous shelf

Gorgeous shelf! I know it’s not real wood but you can’t tell the difference and the price is right! Pipes are beautiful too! My dad put this up and had a little trouble aligning it up with the holes so make sure you have um right before you start drilling them.

Not REAL wood - particle board with veneer - but still beautiful.
Color: 1set, Size: 24inch, Color: 1set, Size: 24inch
Came on time, easy to assemble, relatively easy to install. Metal rods are actually metal, which is nice. Flanges are good quality, very nice rustic look. Shelves are less wonderful. They are definitely not real wood at all. They are cheap particle board with veneer. I would not have purchased had I read more reviews, BUT it is still beautiful, sturdy and does the trick. We can always cut our own shelves if we should so choose and re-use the very nice hardware. 4/5 for misrepresenting as real wood, but 5/5 for functionality and aesthetic.
