The original solid wall THICKWALL jar. This jar, which is very popular with the cosmetic industry, is not to be confused with the lighter, more fragile double wall jars available elsewhere. This jar has a solid feel whether full or empty, conveying a sense of quality to the consumer. Since the jar is of single wall construction, it is impossible for it to come apart during printing, filling, packaging assembly, shipping or end use. The thicker side wall can reduce product loss or weight loss by a factor of 10 in cases where evaporation or drying out is a problem.
