Nowadays every website that deals with user accounts needs a quick sign in/login button. For that purpose, I think these Facebook and Twitter social buttons will come in handy. You have 6 versions in total: normal, hover, pressed (or flat) with a text variation. The custom font used is available on Google and you can use this freebie for commercial purposes. Just don’t say you made them. As always, show your love by sharing it with the world.
