Good quality silicone, quite thick and protective. The built-in clip is nice as a feature, but I'm not sure about its material and durability. The connection between the main part and the case lid is very thin, resulting in it often breaking inward and not allowing the lid to fully open (I eventually cut it off). Overall, though, I am satisfied.

Very beautiful and practical case. And the top part that comes off in other similar cases DOES NOT come off, and it is particularly easy to lose

Good quality silicone, quite thick and protective. The clip it has integrated is nice as a feature, but I'm not sure about its material and durability. Personally, I consider it somewhat dangerous to put it on your keys or bag in this way, and for the case to be flapping around, because it can open and fall off.

I give it 4 stars because it has two small drawbacks. Firstly, there is no space in the case for the back button of the headphone case, so you have to remove the case if you need to pair them with another device. Lastly, the connection between the main part and the lid of the case is very thin, resulting in it often breaking inward and not allowing the lid to fully open.

Overall, though, I am satisfied
