Very nice hidden bracket shelves
Size: 3pcs, Color: A. Brown, Size: 3pcs, Color: A. Brown
Nice shelves and easy to install. Simply put the first shelf bracket where you want, throw the provided level on it and Mark the holes. I had to use the drywall anchors since I didn’t have studs behind the desired location but you might luck out and catch one on your location.
The shelves are really nice looking, light weight and should be a good fit just about anywhere.

Looks great and solves space issues
Size: 3pcs, Color: A. Brown
This is great for a small bathroom. It frees up your counter space and at the same time looks good. You can put your essentials like q tips, cotton balls, etc in decorative containers and add a small plant or sign and you have made your cluttered bathroom look awesome.

Great privacy screen
Size: 6 Panel-119"W, Color: Beige
I have a studio apartment and the bathroom is in my bedroom. I bought this to section the area off so guests can use my bathroom without seeing my entire bedroom. This is perfect for that! It looks very nice and offers alot of privacy. The screen is fabric and good quality! I’m a middle aged woman and put it together myself in about 2 hours. Love this!!!

Nice divider 6 panel with wheels.
Size: 6 Panel-119"W, Color: Black, Size: 6 Panel-119"W, Color: Black
The wall works great , and I put it together by myself. I only gave it what I did because I have to move one or two of the panels on one end around a bit daily to make an opening to pass through. I find I have to check the screws that hold those legs/feet on frequently and retighten them. Beyond that everything was pretty good quality. (I ended up magnetizing an Allen wrench to one of the feet.) I also put on motion lights to the rollers so you’ll see them and don’t trip.
