ZERO regrets purchasing this gorgeous screen!!
Color: Mountains and Waters, Size: 6 Panel, Color: Mountains and Waters, Size: 6 Panel
I am just really blown away by how gorgeous this screen is and I could not be happier with it. It's lighter weight, but still substantial and the print and colors are just exquisite. I would buy this again 10 times over. I can't even believe it just over $200 for a 6 panel screen of this quality and beauty. WELL worth it and the best deal you will see out there for something like this. The screws and the way they work took a little bit of a learning curve, but once I realized what each controlled, it was smooth sailing. The screen arrives fully assembled, but you just need to tighten and loosen is some areas to accommodate your needs for its position and the floor it's standing on. Nothing too complicated at all, just a few tweaks here and there

Don’t get naked
Color: Mountains and Waters, Size: 4 Panel
In low light, you can easily see through the partition, so just know that. No assembly required. Just pop it out of the box. Good product.
