The dispenser seems to be of a generic type that was used by various retailers and companies looking to put their own branding onto products.
On special occasions you want a true vintage blade to authenticate your shave of the day, 10 unused blades in this sealed card, once used, keep the dispenser and place your regular blades into it, sometimes I throw a 'lucky packet' selection of blades in there to make things interesting, once you have a few you don't have any idea of what is coming next!
Certainly not many of these around, grab it quickly, once gone it will be a while until we have one again.
