Seller wendybebs has sold over 15,000 (based on feedback) fake shaving items from P&G. Purchased one myself and although the packaging looks authentic (meaning a large number of people do not realise they are being cheated), the blades are of poor quality and start rusting after a few days.
Over 100 people have reported the issue in the ebay customer feedback but as of today, ebay has not taken action to close the store.
