Carr&Day&Martin  is a UK made skincare brand. Belvoir Tack Conditioner Spray is a glycerin-based soap that will leave a shiny, protective finish on leather. This coating nourishes as well as filling and sealing pores. This helps by forming a barrier against salt, dirt, grease and water, protecting the integrity of the leather. When using on new leather, be careful not to apply too much as this may cause a sticky film to form on the surface.
