not the original [SEP] be careful purchasing this product as there is a legal disclaimer posted for a reason if you have shopped around you will find there are some sellers asking a lot more for this up to those are the ones being sold in the original packaging the hard plastic you pretty much need a chainsaw to get open this version comes in a plastic ziploc bag with a cut out version of the cardboard insert and although the bottles look identical on the surface the ingredients are not the same as the original the original was amazing worked for bad breath after just one use this version not so much it is missing sodium fluoride and propylene glycol and those were apparently the magic ingredients but i believe there is something about those ingredients that caused a problem for some pets which is prob why they stopped selling it and why other sellers are asking so much more for it unfortunately it does not work without them i was not paying attention do not make the same mistake you get what you pay for
