ChocoMaker(R) Natural Milk Chocoflakes 100ml

How difficult do you think it would be to try to make these yourself using a candy bar or something and a knife or other implement? Any suggestions?

When these are fresh and in good shape, which brand of chocolate candy does it tast most like (e.g., Hershey, Cadbury, etc.)?
