This is three spools of Oregon quality chainsaw chain there's a little over a half a spool of 325 and a little over a half a spool of the bigger size for the bigger chainsaws these spools run a little over $300 for the small one Part# 325 and a little over 300 for the big so this is 1/3 the cost and it's brand new don't know the exact length without winding it and measuring it but it's basically a little over half a spool of each size! $100
