Gillette 'Spoiler' blades have a very loyal following under the shaving fraternity, and no serious collector would give up an opportunity to get his hands on some of these. Apart from the collectors there are some users love the blades so much, they buy them up whenever they can to use for their daily shaves, needless to say this will constantly erode away at the availability of these, so use sparingly if you can!
This card of blades seems to be from the late 60's, and is the perfect addition to your vintage Fatboy or similar Gillette razor from that era. More on the spoiler range of blades here.
This offer consist of 10 unused blades in its original dispenser in a sealed card. Once used, keep the dispenser and place your regular blades into it, at times 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!
Enjoy on special occasions using that special razor!
