Wobbly but Usable
Color: Grey, Size: Standard - 4 Panel
A bit wobbly, but good enough for the price when you need a solid background for remote work calls.

Nice and easy to assemble
Color: Black, Size: Standard - 4 Panel
I absolutely love this 4-panel room divider! It was super easy to assemble — I had it set up in just a few minutes. The material isn’t too see-through, which gives just the right amount of privacy while still letting some light through. It does exactly what I needed it to do and looks so clean and sleek in my space. Perfect balance of style and function — highly recommend!

Nice.
Size: Medium, Color: Prime Pink/White Assorted
These were great quality and perfect fit. They held up. Under Armour seems to make the better quality socks than others.
