Made out of carbon steel, the Midnight Edition Rotary Blades are designed with a universal opening so they will fit on other 45mm rotary cutters.
Each pack comes with 5 blades.
Durability can vary from person to person and how one uses their cutter, as well as the type of cutting mat they have. We tested our blades at various fabric shops in Toronto, and after using them for up to 8 hours a day, five to seven days a week, each shop got between 3 - 4 months of use from one blade!
Please note: the blades are coated with oil to keep them protected from humidity during transportation. We recommend wiping them off with a scrap piece of cloth before use to avoid staining your project.
