Razor Blades of this quality are few and far between. These blades are double track blades with lubricating strips. They come 10 blades per box (These blades are "Track 2" blades meaning they slide on from right to left or left to right. They are not like Gillette blades that snap on. They are for use with Col. Conks Double Track Razors and older "Track 2" style razors.)
