Pretty functional
Color: Llight Gray
Looks good and very surprising. But need to check for QA. Mine came cracked on one of the corners and I didnt noticed it. Other than that, I recommend these. Pretty roomy for all your things.

Tray works for me!
Color: Llight Gray
Love this little tray! Sits on my desk and helped eliminate some of the visual clutter by consolidating it into one box. I like the quality of the materials too - if I wasn't lazy, I'd uplaod a photo but alas - today, I'm lazy
