        Simple valet tray that finally keeps my pockets from exploding on the nightstand
        Color: Black, Size: Sectional, Color: Black, Size: Sectional
        This valet tray is one of those small things that makes daily life a little easier. I like the sectional layout because it gives everything its own spot instead of just tossing a pile of keys and a wallet together. The phone slot is angled so you can actually see the screen when it is sitting there, which is a nice touch. The inside lining feels soft so it helps with scratches and it also cuts down that loud clanking sound when you drop keys in it. The non slip base matters more than I expected since it keeps the tray from sliding when you grab stuff in a hurry. Size wise it fits the normal everyday carry stuff without being huge. If you want your entryway or nightstand to look less messy, this does the job.

        Thoughtfully Designed Tray
        Color: Black, Size: Sectional
        Such a simple item, but Spigen was very thoughtful in some of the subtle design feature. This is not just a box with dividers. Each compartment is actually sloped, which makes grabbing an item ergonomic, allowing you to just pull something to the edge instead of the often awkward battle against the walled edges of a traditional design. Yes, it's just a tray, but I appreciate its thoughtful design.

        Keep your essentials all in one place
        Color: Black, Size: Sectional, Color: Black, Size: Sectional
        Picked this up to declutter my nightstand and it’s honestly been a solid little upgrade. The layout is super practical, there are 4 compartments and they’re actually sized well, not just random sections. I can fit my keys, wallet, watch, and random small stuff without everything piling on top of each other. The phone slot is a nice touch too. It’s angled just enough that I can glance at notifications or watch something while it charges. Didn’t even miss having a cable hole like I thought I would. Build quality feels better than expected. It’s lightweight but still sturdy, and the outside has a clean, modern look. The inside lining is soft, so when you toss your keys or watch in, it doesn’t make that annoying clatter or scratch things up. Also appreciate the non-slip bottom, it actually stays put when you grab stuff instead of sliding all over the place. Overall, simple but well thought out. If you’re tired of your everyday carry stuff being scattered everywhere, this does the job nicely. For the price point, this is a great value 👌 👏

        Spigen Modern Valet Tray
        Color: Black, Size: Catchall, Color: Black, Size: Catchall
        I'm a big fan of all Spigen products, I needed something to keep my nightstand as tidy as possible and took a chance with this tray, however I was a bit letdown on its quality. The tray has weird indentations on the very edge, I'm not sure if this is intended or if my product was damaged. The tray has nothing crazy going on, other than it has rubbery feet to prevent from sliding around your area. The size and fit are perfectly fine to keep my wallet, keys and headphones organized. I love the look of it, it has a great professional appearance, just a bit sad that it has those aforementioned weird markings on the edge. Tray was simple to use, nothing weird.

        Soft Catch Tray
        Color: Black, Size: Sectional, Color: Black, Size: Sectional
        Pros: 1. Soft tray. Has almost a silicon type texture. Won’t scratch items you put in the tray. The segmented sections are the perfect size for wallet, keys, sunglasses, watches, etc. Phone section is slightly angled as well. 2. Rubber feet helps it stay in place and doesn’t slide. I have mine on top of my watch winder and it has moved even when throwing items on it. 3. Build quality is great. Has a textured hard bottom and soft inner. Everything has a nice finish. 4. Price is great for the quality received. Cons: 1. The silicon inner material is a dust magnet. Makes it difficult to keep clean. Summary: This is a great option for an organized tray. I am extremely happy with the quality and functionality of what I received. Spigen is always a great brand.
