Ideal for Thick, Viscous Formulas: Jars are perfect for dense textures like rich night creams, moisturizing balms, body butters, and thick masks that would be impossible or very difficult to dispense through a pump or tube.
No Mechanical Stress: The formula doesn't need to be forced through a small pump mechanism. This is beneficial for products containing high levels of particulates (e.g., physical exfoliants) or certain waxes and butters that could clog a pump.
