Choose a high-quality clean, with loop-end mop heads made from a quality 4-ply cotton/synthetic blend yarn. Mop heads provide excellent absorbency and durability, with no fraying, raveling, or tangled ends. 100% vinyl-coated mesh headband provides added strength and stability. Tailband allows mop to cover more floor area per stroke; saving time and labor. Blue yarn keeps mop heads looking like new.
