Super cute landing space for keys
Color: White 1 Pack, Size: 8" x 8" x 1.8", Color: White 1 Pack, Size: 8" x 8" x 1.8"
I always have trouble finding my keys and so it’s been very helpful to have a dedicated spot to easily throw them in when I get home. At first I thought it would be too big but it’s the perfect size for two wallets and keys, and it’s good quality albeit a bit expensive. The gold isn’t too shiny either, it’s a nice touch and it really reduces the look of clutter on your surfaces and helps it look more organized. It also doesn’t slip around.
