Sturdy & Easy to Assemble!
Color: Black, Size: 2 in 1
Does not come assembled - you must assemble it, and once you do, it leans a little forward due to the hanging screws being on the top but on the bottom. It looks as shown, although dimensions are slightly different than indicated. It is 12" wide x 5" deep, and I bought the one that said it was 18" wide by 4" deep. It's sturdy enough to hold hair products and toiletries, or a small plant. Overall decent for price.

love!
Color: Black, Size: 2+1 Tier Size, Color: Black, Size: 2+1 Tier Size
these floating shelves are sooo cute and i love them so much. it took a HOT minute to put them together (prob like 30-45 mins for me), but i can’t explain how happy i am to have them! i hung these once in my last apartment and re-hung again after moving, and they’re still great. the only con is that the rail around the bottom shelf (the part “holding” the L block, plant, and white block in) is a little bent and i can’t straighten it out no matter what i do. it’s really hard to tell, but it’s not quite level with the board beneath it (pic 2). i’m just a perfectionist so it was very clear to me when putting it together haha. nobody else notices it until i point it out, and i’ve begun to overlook it too, but just a little something that i wanted to add.

Perfection in a corner!
Color: Brown, Color: Brown
They're gorgeous and easy to mount. Hands down, highly recommend. They look really high quality and feel that way, too. They fit my corners perfectly, and have a really rich color to them. I'd absolutely buy them again.
