This science and technology-themed card set was created in collaboration with our favorite nerd over at steamnerds.com.
There is a card for any occasion that may pop up.
Have a friend who's sick? Give him a debugged card. Another one aced a hard exam? Give her the good hacker card. There's even a fun fill-in-the-blank style card to say happy whatever you want!
Cards measure 4.25" x 5.5" and the set includes white envelopes.
