Please ensure you are closing your bond tightly in between uses, if you let too much air into the product it can become tacky and dry. This product is designed for professional or advanced QuickLash users. Please ensure you are only using a small amount of bond, and only at the base of the natural lashes. You do not want to apply the bond like a mascara. We recommend giving the bond a few seconds to allow it to become tacky before applying to the eye. Please do not order this product if your country's current temperature is under 0 degrees. The formula cannot withstand cold temperatures & we are not held responsible for any issues that arise following this warning. Store up right in a cool, dry place out of direct sunlight
