Black adhesive is specifically produced for eyelash extensions. Ultra fast drying (4 to 5 seconds). Ultra strong bonding and flexibility. Adhesives fumes and odor are removed to the minimum, so there is less risk of allergic reaction. The permanence is approximately 4 to 6 weeks. This adhesive is liquid. Shake well before every use! The adhesive is of high quality and medically approved. Only for professional use. Color: black. Important! Store adhesive at max 25°C or lower temperatures. If stored at higher than 25°C, adhesive may lose its bonding ability, become sticky and unsuitable for use. For that reason, we do not recommend ordering adhesives to outdoor parcel terminals during the summer hot weather period as high temperatures may affect the product quality.
