Best Containers offers an extensive selection of single-wall clear plastic jars. Made of PET, short for polyethylene terephthalate, these jars offer high clarity and impact resistance, making them especially well-suited for small businesses that need packaging for cosmetics, lotions, creams, clays, slimes, gels, and other products. Many buy them for personal reasons as well and use them to store things like homemade cleansers, moisturizers, and face masks. However, we do not recommend using PET containers to store products that contain essential oils greater than 5% or fragrance oils greater than 15%.
