I have to go along with what 1Porschegirl said - the items are all fakes. Did you know that selling these constitues breach of copyright (without the express permission of the manufacturer, Prcoter&Gamble?)
Oral B Flexisofts and Gillette Fusion Powers are fakes from China. At such a low price they have to be.
If you buy these items you too could be liable to prosecution, maybe jail. It`s best if you don`t buy these. Of course, ebay will deny anything, but they are also implicated in mass theft.
I suggest if you feel unhappy to contact Procter&Gamble.
