A jar is a packaging container commonly used for storing skincare products such as creams, masks, and eye creams. Typically made from glass or high-quality plastic, jars are designed with wide openings for easy dispensing of thicker or more viscous products. Their strong sealing helps preserve the stability of the product and extend its shelf life. With a simple yet high-end appearance, jars are an ideal packaging choice for premium skincare brands, enhancing brand image and product value.
