Gillette Venus Original Razor Blades is a refill pack containing four cartridges. The cartridge features a 3-bladed head for a close, smooth shave, and an aloe vera and E vitamin enriched lubrastrip so that the razor simply glides over your skin. Gillette Venus Original also has a blue indicator strip that fades away when you are no longer getting the optimal shave, that way you know when its time to change the head and can avoid the shaving rashes and ingrown hairs caused by shaving with blunt razors. The Gillette Venus Original cartridges fit any Venus razor handle (except Simply Venus).
