Ariat Unisex Boot Stretch 6.5oz Spray Liquid 6.5 Oz size - Having a bottle of spray with over six full ounces within will allow you to use this spray repeatedly, and for more than one pair of boots. This means your investment goes a very long way. Liquid - Rather than an aerosal mist, this is a real liquid spray that coats the leather and gets down into its pores, loosening it up and causing it to stretch. Multi-Use - Not only does this work great on leather, but it also works well on quality suedes and on reptile skins of all types. Softens - After the first use, your leather will instantly become softer and more supple. It may take a few uses to stretch the boot out, but it will condition the leather instantly. Non-Toxic - This is a spray that will not cause your skin to become irritated or harm your lungs. Use in an open, outdoor space, but don't worry about any damage if used correctly.
