A 0.140 Lt Milk Jug is a relatively small size, typically used for storing and dispensing small quantities of milk. You should be able to find such a jug at most kitchenware stores or online retailers that sell kitchen supplies such as Sunrose Online. You may want to consider a jug made of a durable material such as glass, stainless steel, or food-grade plastic, depending on your preferences and needs. Be sure to check the product specifications and customer reviews before making a purchase to ensure that the jug meets your needs and is of good quality.

A few factors beyond just the size:

1. Material: Milk jugs are commonly made of glass, stainless steel, or food-grade plastic. Each material has its pros and cons, so consider which one would work best for your needs. For example, glass jugs are easy to clean and won't retain odors or flavors, but they can break if dropped. Stainless steel is durable and easy to clean, but it doesn't allow you to see the contents inside. Plastic jugs are lightweight and affordable, but they can absorb odors and flavors over time.
2. Shape: Milk jugs come in a variety of shapes, including round, square, and rectangular. The shape can affect how easy the jug is to pour from, as well as how much space it takes up in your fridge or on your countertop.
3. Lid: Some milk jugs have snap-on lids, while others have screw-on or hinged lids. Consider how easy the lid is to remove and replace, as well as how well it seals to prevent spills or leaks.
4. Spout: Look for a milk jug with a well-designed spout that allows for easy and precise pouring. Some jugs have wide spouts that can cause splashing or dripping, while others have narrow spouts that make it difficult to pour quickly.
5. Brand and price: There are many brands of milk jugs available, and prices can vary widely depending on the material, size, and features. Look for a reputable brand that offers good quality and value for your money.

Overall, a 0.140 Lt Milk Jug is a good choice if you frequently use a lot of milk, such as for a large family or for baking or cooking. Just be sure to choose a jug that meets your specific needs and preferences.
