I was looking for this exact product but didn’t know it! We recently moved into a new home and had zero window treatments so needless to say I wanted something quick, affordable and not vinyl WalMart blinds. We are happy with our purchase and would highly recommend to others. Some complain of the adhesive not sticking- make sure to clean the window wells/walls etc prior to installing these. If the surface is free of dirt/grease there will be no issues with them staying put.

Good value for the money.

Color: Ivory

This is a very good quality set. The plastic is sturdy and the colors are nice. The soap dispenser has a good capacity and shouldn't need refilling very often. The wastebasket is smaller than the one I was using which was rated as a 4 gallon size. I would say this one is about half that. The toilet brush was in 3 parts and was easy to screw together. Since I don't use bar soap, I popped out the drain insert from the soap dish and used the base to put the dispenser in. That will keep it from dripping soap on my counter. All in all, good value for money and I will buy a second set.

Nice but incomplete

Color: Ivory

I think the color and overall look for the bathroom is beautiful. I'm very disappointed that some parts were missing from the package!

Happy with purchase

Color: Ivory

I was pleasantly surprised by the quality of the set. It seems sturdy and durable. The colors were just as pictured and very nice. The brush handle is a bit short, but that is okay. It took me a minute to get the lid flap in place, however, once I got it on it works as expected. A decent value.
