I have bought Frontline spot on for cats x6 pack and as your pics this product is a fake. All the packaging looks good but as you peel back the plastic sheet covering the pipettes you can see how its just been glued down badly . The site is a .co.uk and as link below it gives you the impression you are buying direct from Frontline/Manivella.
