Our cobalt blue glass Boston round bottles are distinctive in their classic shape, with rounded shoulders and rounded base.
These glass bottles have high chemical-resistance levels and extremely high resistance to heat and cold. All of Purple Citrus’ glass containers are lead free.
Cobalt blue glass bottles are great for storing essential oils. The cobalt blue colour is an electric and vivid blue, which provides some UV protection for light-sensitive products.
Covers for cobalt blue glass bottles are sold separately to allow you to customize the look of your finished product.
