Fantastic and elegant looking nightstand or bathroom tray
Color: White 1 Pack, Size: 8" x 8" x 1.8"
I absolutely love this nightstand tray! The elegant gold trim gives it a luxurious look that instantly elevates my nightstand decor. It works perfectly as a perfume or cologne organizer and keeps all my bottles beautifully displayed. I’ve also used one as a dresser organizer countertop to hold jewelry and skincare, and another as a stylish key tray or key holder bowl by the front door. The quality is excellent and the design is both functional and beautiful. I love it so much, I’ll definitely be buying a few more to stack it up in a couple of my rooms. Highly recommend!

very happy with my purchase
Color: Brown-F, Color: Brown-F
The quality and craftsmanship of this tray are amazing! I bought it mainly for jewelry photography, and the results turned out even better than I expected ✨ The matte finish is exactly what I needed because it doesn’t reflect light, which makes photographing jewelry and pearls so much easier and gives the photos a much more elevated look 📸 I took these photos at night under white lighting, and I’m honestly so happy with how they turned out. The background looks clean, soft, and aesthetic. Sharing some of my photos here for reference — highly recommend!

Super well thought out tray. Looking amazing of course and the sizes of the slots are great. I can fit my large phone in the slot and it has a space for the charger on both ends. Love this tray.
