Would purchase again
Size: 48inch, Color: Light Walnut
I was not sure what to expect when I purchased these. I thought maybe they were going to be a fake particle board. But this was a solid wood. Easy to install, no directions were in the box. There was a few chips in the corner of the wood but overall I would purchase again.

Great shelves
Color: Oak, Size: 40"W X12"D - 2P, Color: Oak, Size: 40"W X12"D - 2P
Better than expected! Wanted shelving in the kitchen after our remodel but custom cut would’ve cost us over $500. Glad we went with these. Quality is great, easy to mount. I won’t be coming close to the weight limit but even with pressure they don’t budge. Anchored into drywall and 1 stud. Great price and perfect for our space.
