Package includes 5 blades and one holder. Hot injected molded plastic razor blades designed with two sharp edges used for scraping, cleaning and peeling. Quickly and easily removes undesired materials from most surfaces without damage. They are non-metallic and non-magnetic so they will never rust or corrode and won’t cause interference when used on delicate electronics or electrical components. They are shaped and sized to fit most standard handheld blade holders used for scraping. Due to their non-cutting design, they are safe on fingers even when no blade holder is used.
