This box contains 100 Shark Super Stainless Steel half blades, and is typically sold to professional barbershops for use in their straight edge razors that require a half double edge blade. Made in an ISO2000 facility in Egypt using Wilkinson Sword technology, each blade is individually wax paper wrapped to assure safety, sterility and long shelf life. To avoid rapidly dulling the blade's sharp edge, remember to always rinse it after use, never wipe it. NOTE: We caution against buying a large quantity of any blade before trying it, so we suggest you first purchase the 5-pack of Shark Super Stainless Steel double edge blades listed on this site. $8.50
