The beauty industry has also embraced the practicality of glass jars. Many small-batch cosmetic brands package their products, such as creams, balms, or scrubs, in 40 ml glass jars. The airtight seal preserves the efficacy of the ingredients while presenting a sleek and professional appearance. Consumers are increasingly gravitating towards eco-friendly packaging, and glass jars fit perfectly with this trend. They are reusable and recyclable, making them a responsible choice for those who are environmentally conscious.
