don't think they're the same but then I haven't used a Tesco Personna for ages.
I will have to try some of the real, or should I say branded Personnas at some point,
because I cant really point the finger at the Tescos blade 100%,
I had never used the 'Velvet' DE before and I had been using the Bic things for a good 2 years, so the action could be different and its just taken me a few weeks to get into it, because IMO I get a great, if not better shave with these Velvet's than ever before.
I will have to sort out a picture as I have not been able to find any real info out about them, apart from the Woolworths thing which I also saw from the box I got with one has one of their boxes with it.
Someone might know about them, there seems to be loads on Ebay for quids,
and with a good blade they seem to give a really great shave.
