Perfect size, high quality
Size: 7.7" x 7.7" x 1.7", Color: Black (Metal Silvered)
I had a previous catch all tray that I bought on amazon, it used buttons on the 4 corners to turn a flat cardboard into a tray. Over time, the catch all tray got filled up, not just with a wallet, keys and eyeglasses but eventually business cards and other knick knacks. With all the items inside the tray, sometimes the buttons would start to pop out. It wasn't awful, more of an annoyance. But it was time for me to find a more durable tray. I looked on amazon and added 6 different trays that had "potential" into my shopping cart. Then I carefully evaluated each one and deleted them out of my cart until there was only one left. Some had multiple compartments. Some were larger than this one. I felt the ones with compartments would limit my ability to put the things I want in there. Also, I didn't want it so big that it took up too much desk space. Ultimately, I felt this was the perfect size. I'm extremely happy with it, the quality is really nice and it looks and feels durable. No more loose buttons and spilled knick knacks.

Keeps clutter away
Size: 7.7" x 7.7" x 1.7", Color: Black (Metal Silvered)
This works great to corral all my notes I write on post its or small notes. Keeping them hidden from the desk top b/c or the depth but still visible to me. Much better than keeping on the plotter. Looks great in quality .

Attractive, Simple, And Well-Made
Size: 7.7" x 7.7" x 1.7", Color: Orange (Metal Glided)
I use this as a "catchall". A place to stash things like my wallet and keys when I enter the door, so that I don't use them (I had been prone to that!). It serves it's purpose well. It's both sturdy and attractive, and a good size for a "catchall". Recommended for those like me who need such things.
