Cobalt Blue PET Boston Round Bottles

Our cobalt blue PET Boston round bottles are distinctive in their classic shape. Characteristic of the Boston round are its rounded shoulders and rounded base.

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.

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 unique cobalt blue colour of these Boston round bottles is an electric and vivid blue, which provides some UV protection for light-sensitive products.

Covers for cobalt blue PET Boston round bottles are sold separately to allow you to customize the look of your finished product.
