Is there a way to guess the approx age of these? There is no date but each pack is different. The one similar one is a little bigger. Also do they shave well or better off just putting them on a shelf and not cutting up my face? Thanks
Thanks for the site and info.The super blue blades would be the only ones I would consider using, but they are probably worth more as collectibles in that unopened condition. Here is Achim's Gillette blade page which may help generally date them. The only way to date them exactly would be to open them and look at the date codes on the blades.
