YC-G175 and YC-R175 cream jar and lotion bottle sets are packaging sets that include both a cream jar and a lotion bottle for storing and dispensing skincare products. These sets are typically made of PMMA (polymethyl methacrylate), which is a type of plastic known for its transparency, durability, and resistance to impact and UV radiation. PMMA cream jars and lotion bottles are widely used in the beauty and personal care industries, and are preferred by many people because they are lightweight and easy to use.
