Lower Unit Cost: A simple jar and lid are generally less expensive to produce than more complex packaging like airless pumps or pressurized cans.
Simpler and Faster Filling: The filling process for jars is typically straightforward and high-speed, leading to lower production costs and higher output for manufacturers.
Design Flexibility: Brands can easily switch or tweak formulas without needing to completely re-engineer the packaging, as long as the consistency remains suitable for a jar.
