Great Desk Organizer Trays!
I don't often post reviews on Amazon but these desk organizer trays really deserve a review. These are LITERALLY knock off of Balolo trays at a fraction of the cost with the same quality and craftsmanship as Balolo. I got them with the hope of been able to take the divisions out and glad that I did. Taken the divisions out to use them as paper trays is possible and it is super easy to do with a screw driver taking 4 screws from under the tray. Then you can use them as paper trays. I got 5, three I'm using them as paper trays and 2 as desk organizers. The small tray and the pen holder are also worth getting to complete your desktop/office setup.

Good quality tray - didn't fit my desired use case but I'll still keep it
I bought this tray in place of one that costs more than double the price so the value is there. However, this tray does not fit within the upper tray of my desk shelf - it's probably about 1mm too thick to fit. Despite this, I've decided to keep the shelf because the quality indeed is good, and I just placed the tray under the other side of the desk shelf sitting on the desk instead. It keeps a number of my frequently used desk items organized.

Balolo Setup Cockpit Users: It's Worth a Look
If you own the Balolo Setup Cockpit and have the large tray, this will fit below the large tray with 4" to spare (left to right). It's too deep to fit in the tray; it will stick out the front by about 2 inches. On the desk (below the tray) it hangs about 1" past the tray, but you can't see it because it's in the back. The walnut is a good match. Quality is decent. The felt is cheap, but I guess I can upgrade it on my own, or ignore it. My Balolo is magnetic so it's probably steel. But this product isn't magnetic, so it's probably aluminum. Improvements: It's an obvious rip on the Balolo equipment and they should have done a better job on the sizing to make it more versatile. At 2.5" less deep, 1" less wide, and .25" less tall would allow it to fit in the tray and still allow one of their smaller drawers to fit next to it. Verdict: It looks pretty good and is 1/5 the price of the Balolo drawer and has free shipping. I'm happy with it.

very well made and attractive.
This is exactly what I was looking for. Something slim with a small footprint that I can sit on my desk to keep my cell, small prayer book, ZYN can and earbuds organized. It is very well made and attractive.

Great quality
Great quality and strong build, just big enough to store everything I usually leave on my desk like wallet, keys, glasses, pens, airpods etc. without taking up an intrusive amount of desk space.
