These spare blades are made out of top quality stainless steel and will fit all standard 28mm blades for Prym/Olfa rotary cutters.
The safely packaged blades should be changed regularly, because blunt blades lead to fatigue, inaccurate cutting and damage the cutting mat. Care should be taken when changing blades, for the blades are extremely sharp.
Blades come in a practical plastic box.
