A 250ml glass milk bottle is a small, clear container typically made of glass, designed to hold 250 milliliters of milk or other liquid dairy products. It usually has a cylindrical shape with a narrow neck and a screw-on or snap-on cap or lid to keep the contents fresh. These bottles are commonly used to package and distribute small servings of milk, making them convenient for individual consumption or for use in various culinary applications. Glass milk bottles are preferred by some consumers due to their eco-friendliness and the ability to preserve the taste and quality of the milk.
