Hello Fellow Vault Dweller! Now that you have been accepted into the safe confines of your vault please accept this badge so that you can always know where you belong.
This badge is designed to work with either my pin adaptor or magnet adaptor. Either one should be sufficient to hold this badge onto your clothes/costume. If you wish to use the magnets the ones which the badge is designed around are found here
I can customise the vault number if you wish or go here for a version without a number. Also take a look at the Vault boy version of this badge over here.
