Nice Desk Organizer
Color: Black, Color: Black
This particular desk organizer has the little strips of wood that each have a magnet installed inside them. This allows you to move the wood strips to different locations and adjust the areas to fit whatever size item you want to put in there. It's very easy to just move them around and the bottom of the tray has a nice material in it that prevents scratching the items you place in there. The usable area on the tray is 12-1/2" x 8-1/4" x 3/4" and the overall size is 13-5/8" x 8-3/8" x 1". It fits nicely in drawers or simply having it sit on top of a desk to hold items. It also is made out of good quality and is very sturdy.

Great product quality
Color: Black
This had literally everything I was looking for, but… just too large for the area I wanted it in. Check the measurements and compare that to your actual space. If they had about 1/2 to 1/3 of this size I would snatch it up in a heartbeat. It has a groove for your phone charging cable and the moving magnetic dividers are genius. I’m looking for something to put on my nightstand to allow the phone to charge at night but face down. Extra section for earrings or hair accessories, etc would be great. This has that potential. Just needed it smaller.

Versatile organizer for men or women
Color: Black, Color: Black
This is a just drawer organizer tray or nightstand organizer that is very handsome with wood grain and metal the two bars are magnetic and you can move them around to suit the size of the items that you're placing in the organizer. I think it's a very versatile item that can use by either men or women and it's a decent size and it can fit small pieces of jewelry your phone a few other items if you were organizing your nightstand before bed certainly can go into a desk drawer or a nightstand drawer to suit your lifestyle. I think it was a good value for the money because it is yet another item that can help us be more organized in this busy world.

Simple, hefty configurable small tray
Color: Black, Color: Black
"Hefty" is not an expected description for a drawer organizer. But it is in this case because of the solid metal plate it's made from. You could brain a zombie with this tray and not dent it (the tray... the zombie's the one that would be dented). Guess the material choice does make sense since the two wooden dividers uses magnets to hold positions. A strong bump would be needed to shift the placed dividers. You get some basic configuration choices from the dividers. Including additional (different length) dividers would allow further sectioning options would have been nice. It also looks good too. Like the design and utility. Would also go for a bigger version. Perhaps that one, like this, would have secondary uses... perhaps as armor plating?

Elegant and easy to customize to organize your desk
Color: Black, Color: Black
This desk organizer was higher quality and more elegant looking than I thought it would be, so I decided to use it to hold some things on my dresser. It’s too pretty to hide away in my drawer. The compartments snap into place with magents so you can adjust based on how you want to organize your items. The tray itself is heavy, durable, and well-made. The compartments and edges seem to be authentic wood, and the base surface of the tray is a rubber-like surface that keeps things from slipping while still looking very nice. I like this tray enough to put it on display as a part of my home decor. It’s not only useful for organizing some odds and ends, but is also very beautiful and well made.
