This men's razor box contains 5 anti-friction blades, so you can get 5 blade tighteners at an affordable price. This men's razor box has a good distance for increased comfort. Each additional blade can hold up to 20 blades. The precision trimmer on the back of the shaver makes it easy to touch, which is perfect for combing random facial hair. Soft particles gently stretch and soften the skin, so your hair can be scraped very close to our best blades (the first four blades), and the lubricating strip helps glide over the skin more easily. The lubricating strip is a thin strip on the top of the shaver, which releases lubricant during shaving to achieve good sliding. When you are no longer getting the best shaving effect, the Lubrastrip will turn white, indicating that you may need to replace the blade. All Fusion5 handles can be installed on all blade parts (except Gillette Laboratories).
