Great for center weight headphones
Color: Walnut Wood
Easy to install for the wall, hang headphones well. Make sure your headphones are center weighted as otherwise they can slide easily

Snack pack
It’s okay for a quick little snack. The package was fresh. Texture was crunchy. You may enjoy it, but you would have to try it on your own. I felt like I was missing something or wanting more.
