(pk of 36) 4 oz Black PP/PS double wall round base jar with 70-400 neck finish w/ Black PP 70-400 unlined dome lid

 4 oz Black PP double wall round base jar with 70-400 neck finish. Double wall jars are 2-piece containers: the shell and the liner. It is called "double wall" because the two containers nested inside of each other create two walls. This jar has a rounded base. This jar is made of polypropylene (PP). PP is light-weight, durable, flexible, and highly resistant to fatigue and heat. It has a high shatter-resistance rating. This is a great container for products containing essential oils, so long as the ratio of oil to product is low (around 5% or less). This jar is typically used for lotion, cream, serum, gel, putty, clay, hair products, skin products, cleanser, and other personal care products. This jar has a 70-400 neck finish, and will fit closures with the same finish.
