You're looking at 180ml (6 fluid ounces) of leather adhesive, the bottle comes with a convenient nozzle. Also great for wood and paper.
This water based adhesive is excellent to bond your leatherwork.
Simply apply to the side of your leather you wish to glue, then press together. Dries clear and hard. Should any excess glue remain on the edges of your leather, gently rub off when slightly dry.
