The advert states: 100% genuine buy with confidence
When my item arrived and I opened the jiffy bag I found it was in a clear plastic bag, with no other packaging or instructions etc.
As this was fulfilled by Amazon I contacted them to confirm that this item was genuine. They responded and said they would ask someone in their fulfilment centre to carry out a physical check. They later came back and said that they had received an update from their fulfilment team and could not confirm whether the item is fake or genuine and requested that I return it!
I am not sure that I can buy through Amazon with confidence any more! I had hoped as it was fulfilled by them it would be safe.
