A high-quality stitched patch, similar to ones you'd get in scouting, or for other achievements. Not iron-on. Must be stitched. Looney Labs backed a Kickstarter from GamerBadges.com to have these made, and we're really happy with them.
Since they were made as part of a Kickstarter from another company, we don't know if we'll be able to get more when these are gone so get one now, while you can!
BUT we request a max of ONE PER CUSTOMER (unless you have some reason you need more than one. Feel free to explain your mitigating circumstances in the Special Instructions on your order.)
