Sample packs are how we got started and a critical part of the process for the novice wet-shaver. Our range of blades is extensive, and the difference from one to another is extreme. The best and only way to find the perfect shave is to try different double edge razor blades, as each person's experience is unique. Each package contains quite a few blades--we think it's a great deal! Instead of using an entire box from one brand, we recommend rotating from brand to brand, as you may have a different opinion on a blade after trying a few other brands. On the packs that include a Feather blade, we always like to note that it's the sharpest and best to try last! All fit our wide assortment of safety razors.
