BacTrack Portable Breathalyzer KeyChain (Black)

This is The New BacTrack Portable Breathalyzer KeyChain Retails $39.99 most stores. Only used once so there's No Package. Also No Wear & Tear that's Noticable as far as I can tell. The BacTrack itself is about 3 inchs long and 2&1/2 inchs wide and has the keyring attatched so that u can take it with u anywhere. (Probably gonna need new batteries to assure 100% accuracy)
