You see the Green colored insignia on the Dollar Bill? THAT is were we suggest attaching the plastic snap on the Dollar Bill. (See the little red dot in the middle of the green insignia?) That is the least conspicuous location to attach the plastic snap. If you attach it outside the insignia the snap is more noticeable to the victim.
We recommend purchasing a BRAKE KIT which also includes additional SNAPS in the kit.
(The BRAKE KIT can be found in the Joke Items section here on the website)
