Great quality, easy to set up.
Size: 3 Panels, Color: Grey, Size: 3 Panels, Color: Grey
I actually have this in my bedroom, replaced a non acoustic panel with it. These make a huge difference. As someone who is always playing music on their speakers I don't want to bother my roommates too much. Easily can hear the difference once these were in place. The panel itself is high quality and thick, what's a really nice detail is how they are attached together, there are multiple wedges just like foam noise dampeners which is super cool! This thing is easy to move around and can be folded for storage with ease. You get extra screws just in case you lose any, the feet are made out of metal which adds to the quality. There was a very slight chemical smell when taking it out the box, however that went away in just a few hours. I can imagine using this in a noisy office, surrounding yourself with these in a cube shape will make all the difference to focus on your work. These panels are great and if you're looking for quality, I'd say you can pick these up without worry. No issues on my end!

Office Divider
Size: 5 Panels, Color: Grey
This office divider is well made and easy to assemble. All you have to do is install the feet. The panels are only about an inch thick, but they work surprisingly well at muffling unwanted background noise.

Easily Create a Workspace
Size: 5 Panels, Color: Grey
Such a great design. I am loving the versatility of these - very easy to set up and also to store. THe color is perfect for them to blend into the decor. While they don't cancel out the noise altogether, they reduce it and decrease distractions. No installation needed - has its own supports. Built really well with good materials - sleek and sturdy and solid. They have increased the privacy and have helped make a great space without difficult construction. Work well and they are great value for money - instant privacy and space.

Very good product
Size: Medium, Color: (001) Black / Black / Pitch Gray
I purchased these to wear inside lowcut slip on casual shoes, I don't particularly like to not wear socks in my shoes for hygienic reasons. Prior to purchasing these socks, all I could find were those made of very light beige hosiery type material , and my slip on shoes would slide around a bit. These are light weight and breathable athletic type material, with a very good gripper strip at the heel. One pair of my slip on casual shoes have a particularly lower cut in the toe area, but the shoe is black and I chose the black color and though I see a hint of the sock there, it matches and does not detract from the look of the casual solid black shoe
