This is a 118ml bottle of Fiebings Leathercraft Cement, a very popular and affordable glue which is useful for a wide range of leather and craft projects.
Fiebings Leathercraft Cement is a flexible, non-flammable adhesive which forms a high strength bond for leather, cloth, chipboard and paper based projects.
To use, spread a thin layer on both surfaces to be bonded. While the glue is still slightly wet, press both surfaces together and keep pressure on the bonded surfaces until the glue is dry.
