A durable and reliable solution to protect your Apple TV 4K remote
Color: Black
A simple but rugged and durable case for such a fragile and expensive item. The case offers great padding and support for the remote. It fits perfectly over the shell of the device but adds little bulkiness to the overall feel. It is compatible with the most recent iteration of the Apple TV 4K remote. The buttons are easily accessible on the front and the case does provide ample support for the Siri button on the side. Depending on which color variant you choose, the case is easily visible when you inevitably drop it on your bedroom/living room/entertainment room floor.

So well made you could mistake it for an Apple designed case
Color: Black
I searched Amazon for a remote case with touch control sensitivity and this looked like the best option available. I did not check specs, that’s on me. When I received it I realized it wasn’t what I had hoped for. I am glad for the mistake, this keeps the back of the remote scratch free. The case fits so well it could be mistaken for an Apple made case. The edges are raised just enough to protect the controls. It has a nice feel to it and it’s easy to grip without fear of it slipping out of your hands.

It is really well made and perfect for travel!
It is just like the picture and it is lovely. Plenty of room and under the tray it is large enough for changes with pendents.
It is perfect for a girl and will be perfect for the amount of jewerly you take when traveling.
Thank You!

Very nice little box.
This is a great little jewelry box. I don’t have tons of jewelry right now, so this fits everything well, and the leather-look material is very nice. I like the simple design and organization, and it is a nice size to travel with. It looks really pretty sitting on my dresser and goes with the aesthetic of my home well.
