All-Purpose Saw MAP Blade M Replacement Blades for PVC, 2 blades per pack x 4 packs Total: 8 blades My carpenter grandfather had purchased these. Please be aware that these have been stored at home for a long time and may show signs of deterioration or dirt. Please only purchase if you are comfortable with this. The outer packaging is noticeably dirty, but the replacement blades themselves are in good condition. I am a novice, so I cannot provide a detailed assessment of the condition. Please refrain from canceling your order after purchase.
