Emoji Keychains (ok, fine... they're mostly emoticons)

Is THIS what they meant by "Internet of things"?!
Now you can literally wear your <3 on your sleeve or show your >=( by sticking a 3D printed tag on the thing that makes you angry.

With a little imagination, the possibilities are endless. Plus, these little guys print out really quickly and barely use any filament at all, so you can emote all over the place even when you aren't connected to the internet.

...and as long as certain unnamed commenters want to get technical, there actually is a smiley emoji hidden in among all those emoticons. Have fun!
