High quality divider, but at a high cost
Color: Nocturne
So if you've ever been into an office setting you've likely encountered some variety of this divider. There's a bunch of good things about this product. -It's a nice size -There are great color options, went with Nocturne and no regrets with that -It's sturdy with a good base -Offers a bit of sound deadening The biggest drawback of this product is the cost. It's pricey for ONE divider. I'm sure it would make a great set, although for me it would fiscally irresponsible.
