This 2 1/4" pin back button reads:

"Keep calm and test on!"

A nod back to the Portal games on Steam, this is a hilarious button to wear at school or work as most will figure you're referring to something logical in the real world with a dry sense of humor - only fellow gamers will know that you're referring to Glados from Portal 1 and it's sequal!

Great for any gamer with a great sense of humor!
