Our cobalt blue PET cosmo round bottles, also called bullet round or imperial round, have a tall and slender build with steeply rounded shoulders.
These bottles are made of polyethylene terephthalate (PET) plastic, which is of the polyester family and has high clarity, good chemical resistance, high impact resistance, and medium rigidity.
PET is also light-weight and is used for products containing essential oils, however we advise you to avoid using PET containers to store products that contain essential oils greater than 5% or fragrance oils greater than 15%. If your oil percentages exceed these respective levels, please consider using glass.
The cobalt blue colour is an electric and vivid blue, which provides some UV protection for light-sensitive products.
Covers for cobalt blue PET cosmo round bottles are sold separately to allow you to customize the look of your finished product.
