It came with original pack and leaflet which had barcodes and batch numbers. The tamper proof seal was obviously broken on the orginal box so they could flat pack it. Didn't know you could check if a product was kosher directly with a manufacturer. Be a fun phone call with them 'errr...yeah I bought some medicines illegally online...errr can you tell me if they are legit?'. Maybe able to do this online but not looked into it.
