I am selling a batch of Mirka Shark Runblades that were forgotten in stock for approximately two years. They are brand new and have never been used, but due to non-optimal long-term storage (approx. 2 years), some of the blades show COSMETIC SIGNS OF SURFACE RUST. CHECK ALL THE PICTURES! This is strictly a cosmetic issue and DOES NOT affect the sharpness, cutting ability, or overall functionality of the blade.
