A nice customizable organizer.
Color: Black, Color: Black
This is a nice organizer for a drawer or nightstand. Comes in a box that is not overly bulky and is well protected. It's quick and easy to adjust and put together. the seperators are magnetic so you can customize it to fit your needs. There are two cut outs for charging cords and it fits a phone easily along with other accessories. The unit feels solid and well built, it has a good weight to it. I do wish the deviders were a bit easier to get square, but that's more just my idiosyncrasies.

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.
