While there are no estimates available for Canada, our friends to the south landfill ~2 billion razors each year. Opt for a reusable razor and be part of the solution instead.
Made in the States, the Leaf razor has zero learning curve. Place one, two or three half-blades in and get shaving. To break the blades in half, leave the blade in the paper wrapping and fold in half. Each leaf comes with 20 blades (40 edges).
Care: Don't keep in the shower. Let dry completely. Use a stand if you please.
