Anyone knows what plugin is this?

Hi,
I found plenty of share button plugins for WordPress, but I can't exactly find something like this



I want it exactly like that, text and colors only stretched, anybody can help, please?

If you have a post where you found it, I can check the source and see if I can find the exact plugin. Feel free to PM a link if you don't want it public. I do know there is a plugin, AddThis I think it's called, that I've used in the past that lets you use custom buttons. That could be an option too. To be honest, they look like they aren't really a plugin and are just css buttons, so you can also look for just a customizable button plugin that's not geared towards social, but just buttons in general.
