3 year anniversary is leather
Color: Brown +Wireless
I bought this for our third year wedding anniversary, as a gift for my husband. The 3rd year is supposed to be a gift inspired by leather. The tray is very durable and has lots of compartments. My husband uses it on his nightstand to keep things that he has in his pocket when he empties them the end of the night. The wireless charger is very convenient, although he prefers to actually plug in his phone rather than wirelessly charge it. The charger cable itself is surprisingly of great quality. The leather isn’t too bad either. Good gift for the price point.

Simple and Effective Remote Organization
Color: Black, Size: Small
The Pros: Spacious Design: With five deep pockets, there is plenty of room to store everything from TV and soundbar remotes to reading glasses. Functional and Steady: It sits perfectly on a side table without tipping over. It does exactly what I hoped it would do by keeping all our remotes in one spot. Great Portability: It is lightweight enough to move around easily, which is helpful for keeping things organized while we are on the move. Clean Finish: The material looks professional and blends in well with the furniture without looking like a cheap plastic holder. The Cons: Pocket Depth: One thing to keep in mind is that the pockets are fairly deep. If you have very small remotes, they can slide down a bit far, making them slightly trickier to grab quickly. Bottom Line: This is a straightforward, no-fuss solution if you are tired of losing remotes in the couch cushions. It is well-made, looks good, and simply works. I would definitely recommend it to anyone looking to declutter their living space.
