Another blade that promises great performance by name, with very little 'technical specification' to back it up. Most blade manufacturers do not provide specs for their products and I think this is a good thing, as blade feel on your skin cannot quite be described in a technical sense, you got to try them buggers to see if they are a fit for your skin and stubble. a Good comparison is this V12, how would you ever know if you like driving it unless you have driven it?!
Try them, R18 won't even buy you a single Ricoffy, or a 1/3 cup of Cappuccino !
Each pack has 10 blades in it.
