Excellent tray
Color: Sand Brown, Size: 9.5in x 7.9in
This is an exceptionally high-quality tray. The design was well thought out and it looks amazing. I keep it in my top dresser drawer to organize extra cards for my wallet, my watch, cufflinks, and other items. I can’t say enough about the high level of quality. It stays in place, has great storage and very reasonably priced I thought.

Luxurious
Color: Sand Brown, Size: 9.5in x 7.9in
Firstly, I was very impressed by the packaging and attention to detail, from the box to the lovely wrapping. I purchased the brown and the tray is beautiful with the two-tone. I love the tree imprint on the inside. It looks very rich and the leather has a great feel to it. I also like that the logo was imprinted at the bottom/back. This would make a great gift. Great product!

Perfect for a vanity or shelf! You can easily get to all of the stuff in there too!
Color: Bright White, Color: Bright White
Perfect for all my face stuff. It has a lot of options for placement of things. It’s sturdy. The drawers slide in and out really well. I love the white too. It’s clean and sleek looking. Really happy it stores Medicube products! Wasn’t sure if it would! 🤍

Exactly what I needed! Stores a ton!
Color: Black
PERFECT! This is exactly what I was looking for to organize and de-clutter my bedside table. I have a ton of "lotions and potions" because I'm a beauty product junkie (and as we all know Amazon is a beauty addict's best friend, so needless to say I've accumulated a lot of products). Let's just say my bedside table looked like an Ulta had exploded. I hunted around for an organizer, but none of the others were quite to my taste or needs. This one, however, is absolutely perfect! Despite being made of your basic black plastic, it feels surprisingly well build and has some decent weight to it. The drawers slide perfectly and there aren't any of those little manufacturing imperfections that you sometimes find on plastic products like this. The spaces are all structured in a way that allows plenty of space for a variety of products of different shapes and sizes while still holding them all securely. The top/back (right side) slot is divided into 2 equal sized compartments that easily have enough room for things like full size lotion bottles, hair spray, etc., the middle slot is just one open space and also has plenty of room for full size products or styling tools, and the lowest/front slot is split into 3 equal sized compartments that are perfect for things like smaller face lotion bottles, essential oils, lip balms, nail polish, etc. (you can fit several of such smaller items in each of the 3 lowest compartments). The drawers are surprisingly generous in their size! I was able to fit a ton of whitening strips, full size nail files, hair clips, tweezers, and much, much more in each drawer. Then you have the upper left side which also holds a ton of items (I have all of my serums, facial cream jars, eye makeup remover pads, and some essential oils up there). In fact I was quite shocked and pleased to see just how much this organizer was able to hold, yet it doesn't feel too bulky or oversized. I couldn't be more happy with this purchase! Well worth the $20 in order to keep my table looking sleek and my products easy to find. :)
