In lieu of harsh chemicals, Gleener Dryer Dots harness the natural properties of wool for eco & effective fabric softening that shaves dryer time by 15 – 30%. Softens, separates & fluffs fabrics naturally with their gentle (and uber quiet) tumbling motion. Saves time, money & energy by 15-30%; 100% wool composition soaks up excess moisture and increases the air circulation in your dryer. Fragrance-free & hypoallergenic; safe for those with sensitive skin, asthma, and allergies. You can even use them to soften baby clothes and cloth diapers. Need we say more? Fabric-friendly: gentle on all dryer-friendly fabrics, leaving behind no icky chemical residues. Durable and re-usable; guaranteed to last 1,000 loads – that's three years worth of laundry!
