The one in that picture is 2.5 ml which is outragiously priced.The Ciprofloxacin drops that they sell are expensive, and I think their website shows a 10 ml bottle, but if you offer it you might get a 5 ml bottle instead.
The 5 ml one here that is genuine is $10.49, but again they would have to contact her vet.
