Who expects no original ...

... Will also experience no disappointment.
Differences to the original:
No catch, which must be specially removed
Foil transparent and more rigid, less flexible and tear than the original easier
No red stripe, which warns of the end, this comes suddenly
Fertility identical to the original, but not productive with security
Odour seal as the original
Price difference - compared to vendors in which I have otherwise purchased the original for years - marginal (cents range)
