Both Bluebird adhesives have a longer working time than similar products and are manufactured with ultra-refined rosin for an invisible finish and easy clean-up from hair lace goods. Adhesive X is gelled for added body, yet specially formulated to thin out on skin contact for an invisible matte finish. Less drips mean it is great for facial hair appliances and general application. Tap for eXtra strength and matte effect. Brilliant for on-set too!
