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.

These are a good choice
Color: Black-2 Set
These are great. They are made well, look nice and are easy to move when I’m dusting. I use these to keep perfumes, lotions and vitamins organized atop my dresser. The velvety compartments are a well sized and the layout is conducive to storing the kind of objects women or men typically store atop a dresser. I find these bins quite functional. I feel like these were a good value. They weren’t the cheapest and they weren’t the most expensive. They look nice and feel high quality enough.
