Keep your fabric cuts sharp, precise, and effortless with the genuine OLFA 45mm Rotary Replacement Blades (RB45-5). Packaged in a convenient 5-blade value pack, these professional-grade circular refill blades are manufactured in Japan from premium tungsten carbide tool steel.

The 5-pack comes in a reusable plastic protective carrying case to safely store fresh and used blades, preventing dulling and protecting your fingers during blade swaps. Perfect for quilters, dressmakers, crafters, and industrial textile cutting, these sharp replacement blades ensure clean cuts every time while prolonging the life of your rotary cutting mats.
