Boston Rounds Glass Bottles have a rounded shoulder design that has proven over the years to be one of the most reliable for containing almost any liquid or solid. Clear glass bottles provide a very professional display and are perfect for storing materials which are sensitive to degradation from light. Oftentimes used to store essential oils, they are also ideal for storing chemistry and laboratory chemicals, perfumes & colognes for travel and as a dispenser for medicine cabinet items. This Boston Round Bottle comes with PolyCone Lined Cap.
