Cheap Lee Valley Yellow Plastic Razor Blades

Harder, less flexible and more brittle than the orange plastic razor blades, these straight-edge blades are suitable for removing stubborn substances from glass and tile where the rigidity and increased durability are advantageous.

You can exert more force through the blade edge, but they are more prone to breakage under pressure perpendicular to the blade face.

The blades are 1 9/16″ (40mm) wide and fit the 2 3/8″ and 6″ holders (sold separately) as well as many standard razor blade holders.

Sold as a package of 30 blades in a dispenser that also captures used blades.
