How to use the PF PRO Bond adhesive. Apply our PF PRO Bond adhesive to the base of your natural lashes. You can apply it like a mascara if you want to cover the tips as well. Then proceed to applying the lash clusters either underneath or on-top of the lashes. We recommend adding them underneath for optimal results. Squeeze the lashes into your natural lashes to ensure full adhesion. Once you have finished applying the lashes, use the clear sealant at the base of the lashes for the optimum results. This glue should be used with the PF PRO and the PF DL lashes. 5ml Glue and 5ml Sealant *This glue is Cyanoacrylate free. Ingredients - Aqua, Acrylic Copolymer, Talc
