Ideal for Thick, Rich Textures: Jars are the perfect vessel for dense, viscous formulas like night creams, moisturizing balms, body butters, and thick masks that would be difficult or impossible to dispense through a pump or tube.
No Mechanical Issues: The simple design has no springs, valves, or pumps to clog or break. This is a significant advantage for formulas with high concentrations of particulates, waxes, or certain thickeners.
