Here's a vintage Silver Star Double Edge Razor Blades set in unopened cellophane in a special faux wood block package. I believe these are from the American Safety Razor Corporation and includes 5 Made in USA razor blades.This Advertising Shaving collectible was my father's and I think it would have come from the 1940s or 1950s. These vintage razor blades are not recommended for use. The package measures approximately 2,75 in. by 2 in. by .375 in. The razor blade box is silver with blue type and slides out of the rectangular block (I at first thought the block was wood, but upon closer inspection it appears to be layered cardboard). Very good to excellent vintage condition. Please see my other items.
