Suction cups aren’t the best
Color: Black+Smiley Face
The suction cups don’t hold and my smiley sponge isn’t snug on the post so it sometimes falls off.

Sticks and stays in place!!
Color: Black+Smiley Face
Love love loveeee this! Took me a while to find one that actually sticks and stays in place.
I've had mine for a few months now. Looks just like the photos & comes with the suction cups and an adhesive strip if you want a firmer hold.
The suction cups work just fine.
Would recommend 👍🏾😁

great shelves
Color: C. White - Modern Minimalist Style, Number Of Shelves: 3, Size: 36inches
These are a a great set of floating shelves! They were easy to install, feel sturdy, and look clean and modern on the wall. The set of three is perfect for displaying decor, photos, plants or small storage items while adding extra space without taking up room. Great quality, stylish, and a simple way to upgrade any space. They work perfect for my figurines to be displayed.

Easy to hang and look great in my office. I love the little divot along the edge. Helps to keep pictures from sliding.
