PET cosmo bottles are perfect for products such as liquids, hair care, personal care products, and essential oils. Avoid using PET-style packaging with products that contain essential oils greater than 5% and fragrance oils greater than 15%. If your essential oils percentage is above the recommended limit, we would highly consider using glass. You can pair this cosmo round bottle with any closure that matches a 20-410 neck size.

These variations of amber color provide levels of UV protection for light-sensitive products. Pair this cap with one of our great "Matching Items" below.
