Preserve Shave 5: Made with love and recycled plastic Preserve Shave 5 is a next generation razor that is beautifully designed to offer an extraordinary shave while being light on the earth. What does it mean to create a unisex razor? For us, it meant designing with you in mind, no matter who you are or how you shave. Preserve Shave 5 is designed to not only accommodate but work well and feel good with the various grips used by shavers of all stripes. Preserve Five Blade Replacement Cartridges, Wave Edition: An alternative to the original “Shave 5” cartridge, the Wave Edition “Shave 5” Replacement Blade offers a slimmer design and a lower profile lubricating strip. It is designed to offer an exceptional shave for men, women, and shavers of all stripes. Face shavers in particular report an increased sharpness and a closer shave. Cartridge also includes a mustache trimmer on reverse side. These cartridge replacement blades are designed to fit Preserve "Shave 5" Razors and POPi “Shave 5” razors only. (Will not fit Preserve original Shave 3 Razors.) Never tested on animals. Make your blade last longer: To ensure that your blades last as long as possible and reduce your environmental impact, rinse and dry after each use to preserve blade sharpness and longevity and store outside of the shower.
