You've got to check out this crazy fidget puzzle pen on Etsy - https://www.etsy.com/listing/718506206/fidget-puzzle-pen?ref=shop_home_active_1. It's a mechanically actuated ballpoint pen with a brand new simplified locking mechanism that's so much fun to play around with, you'll probably drive your coworkers totally nuts! They won't know what hit 'em when they see you scribbling away with this thing - and trust me, it's going to take some explaining. The best part is, nobody will have a clue how to even use the thing.
