4 oz Glass Boston Round Bottles

Our 4 oz. glass Boston round bottles are suitable for both wrap labels and front-and-back labeling. The classic round design features smooth, cylindrical walls, making it easy to apply labels evenly and securely. The consistent labeling surface works well with pressure-sensitive labels, shrink sleeves, or custom branding applications. This versatility makes them ideal for product lines that require a professional, polished appearance.

These 4 oz. glass Boston round bottles are compatible with both automated filling lines and manual filling operations. Their uniform shape and consistent neck finishes are compatible with a wide range of filling equipment. At the same time, they are equally practical for smaller-scale or hand-filling processes. Many of our options can be paired with accessories like droppers, making them easy to fill and dispense products such as essential oils, tinctures, and personal care liquids.

Our standard 4 oz. glass Boston round bottles hold approximately 4 fluid ounces (118 ml) and typically feature a 22 mm or 24 mm neck finish, depending on the specific product. While exact dimensions can vary slightly by style and color, all 4 oz. glass bottles maintain a compact, easy-to-handle size with an iconic rounded shoulder and base.

At The Cary Company, we offer a diverse selection of 4 oz. glass Boston round bottles in multiple colors and styles, including clear, amber, cobalt blue, and frosted options. We also provide compatible closures and dispensing solutions, from standard caps to child-resistant droppers, making it easy to configure complete sets of Boston round glass dropper bottles.
