There are tons of Batman keychain/keyring holders but this one has no flip-sides you have to worry about while printing! Just put a key ring through the hole on the side and you are good to go on your new Batman Keyring!
You can find some cheap key rings in dollar stores like 'Dollar General' or 'The Dollar Tree' or on Amazon; here is an example on Amazon.
Do give this a like if you plan on making one and remember to post it under the 'I Made One' section under this Thing page.
