Great price, very cute
Color: White
I purchased this cabinet for the laundry room. Overall it's a great product, especially for the price. I put it together by myself and it took about 30 minutes. It does come with all the hardware you need to install but I used my own hammer as it got the job done quicker. I would caution that mine came with a lot of sawdust. I ended up using the backboard for a dust collector and then ending up cleaning it at the end before install. The size is great for what I need.

Satisfied buyer
Color: White
Easy to install and hang. Material are nice and definitely look more expensive than the price. Good size but not great; suitable for jars bottles/toiletries. Not big enough for towels or thick hand towels.

Primed. Not painted!!
Color: White, Color: White
Pros: price is good. Seems sturdy enough. Size is nice. Easy to hang on wall. Cons: be prepared to paint this cabinet. it’s primed only. There is no finish coat. Looks kinda rough, Dirty and unfinished. A coat of paint will fix this issue. Install was a breeze until I got to the backing of the cabinet. You have to nail 20 finish nails with this dinky little hammer that’s provided. I was actually cracking up laughing the whole time cause it felt so silly. Took a long time with the toy hammer… once I got my real hammer all was well.
