SK-11 Versatile Saw MAP Blade P Replacement Blades for PVC, Set of 2, 5 packs + 1 blade Total: 11 blades My carpenter grandfather had purchased these. Please understand that these have been stored at home for a long time and may show signs of deterioration or dirt. 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.
