Set of 4 safe, zig-zag scissors These are over 30 years old. I found them very useful when I was a nursery school teacher. I tried cutting cardboard with them, and the sharpness seems to be fine. These are the Gizzacco Namicco Marucco scissors from Hasegawa Cutlery. Hasegawa Cutlery, a company specializing in scissors, developed this original product (patent pending) ahead of the world. It's a big hit, with over 5 million units sold in the series. These are the original zig-zag scissors made in Japan. They use stainless steel blades, so they can cut thick paper cleanly. Adding an accent to the edges of message cards or photos transforms them into stylish, unique works! They are great for wrapping, crafts, and more! These are ZIPPER scissors from Fiskars. Fiskars is a Finnish manufacturer of cutting tools. Please refrain from purchasing if you are concerned about long-term storage. Thank you for looking.
