[![after taking out of the handle](https://i.stack.imgur.com/y3AJh.jpg)](https://i.stack.imgur.com/y3AJh.jpg)[![enter image description here](https://i.stack.imgur.com/UPHRx.jpg)](https://i.stack.imgur.com/UPHRx.jpg)[enter image description here](https://i.stack.imgur.com/sv4vB.jpg)One of my sink faucets in my bathroom is leaking and I decide to fix it. I can uninstall the handle using allen wrench but then don't know how to find the O-ring or something. I need to know the brand but I couldn't find any logo on it. I need to know the brand no matter whether I will fix it or just go buy a new one (to be the same). Can someone help to identify the brand?
