Our French Square glass bottles are a great option when space is a concern. The square shape helps maximize your shelf storage space so you can fit more in an area. They have a larger opening than the Boston Rounds, which provides more options for collection of samples, storage of food, or filling of your product. Glass bottles keep your product pure and secure, and they are environmentally friendly as they are recyclable. These bottles are perfect for retained samples, and the color is flint (clear). Remember, caps are sold separately.
