Vintage box, BLU STRIKE BLADES Double Edge razor blades Blue Strike Blade Co. New York N.Y., in n-mint unused new old stock condition. I purchased these from a person who worked for the company that made them in the 1930's - 1960's. They have never been folded up or had any blades in them. Few scuffs/spots. Size is 1 1/2" x 3 5/8". Scans show both sides. The black border is so all the edges can be seen and is not part of the box itself. NOTE: All of the product advertising boxes I have listed are guaranteed to be 100% authentic originals. They are all clean, unused and new old stock unless otherwise noted. Thank you for your purchase I appreciate it.
