These spools are great to have handy around your farm or greenhouse. Use to tie up crops or to give large potted plants extra support. Made of 100% natural jute, each roll is 3 ply and measures 250 ft long. Natural Jute is biodegradable, so any pieces left in the garden after the season will break down and not become tangled in machinery. Spools are designed to fit our Quick String Dispenser.
