FlexBall Technology makes maximum contact over facial contours to give you Gillette's best shave 5 thinner, finer blades for less tug and pull (vs. Fusion) Precision Trimmer on the back for accurate edging Enhanced Lubrastrip with more lubricants and a touch of mineral oil All Fusion razor blades fit all Fusion handles Most men who shave regularly complain of missed hairs, and that too in the highly contoured areas of the face. Thats because while razor pivots usually offer two-dimensional movement, our faces are essentially three-dimensional. Hence all the pulling and stretching to make flat surfaces where there isnt one. Introducing the Gillette Fusion ProGlide Razor with FLEXBALL Technology, a new era of shaving technology developed with over 5 years of research and extensive trials with volunteers across the globe. The FLEXBALL Technology allows the blades to pivot front to back as well as from side to side (up to 24 degrees). This ensures that the full width of the cartridge gets to be more evenly in contact with your jawline, getting virtually every hair. And with the pivot in motion more than 80% of the time, it relieves your wrist, elbow and shoulder joints of the extra pressure. In other words, the razor puts in all the effort, so you dont have to. And what you wake up to every morning is the most precise, closest and effortless shave.
