Arrived damaged
Color: Black, Size: 4 Panel Basic
Unfortunately, very cheaply made. It arrived with one of the connecting tubes cracked horizontally. Possibly due to bad welding. It is quite a headache to assemble. It was delivered on time but returned for a refund.

Not a great experience but a fine product
Color: Black, Size: 4 Panel Basic
not enough screws were included to make the wall. I was able to locate more screws to finish building-so I didn’t have to return the product- but it was a pain and I got lucky finding the pieces I needed but it could’ve been a fail and a returned product

Useful, simple room divider
Color: White, Size: 4 Panel Basic
All the pieces were accounted for, and some even had extra pieces, maybe just in case they need changing. It was a bit like putting together a piece of IKEA furniture, though I went slower than usual so as not to make any mistakes. It wasn’t too hard to put together myself, and helps give my studio apt a feeling of space and privacy for my bed. I only wish it had a lovely Japanese design on it, but it does amazingly seem to match the wall color.
