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.

They look good and seem well built.
Color: Brown
These are very well made and look really good. They ended up being too small for my need, but that was my fault on measurements. I would highly recommend if you are looking for corner shelves.
