Mechanical Design: The egg timer typically features a mechanical design with no need for batteries or electricity. It works based on a simple mechanism that measures time through the flow of sand or liquid from one chamber to another.

Visual Indicator: The timer usually has markings or indicators on the outer casing to indicate different levels of egg doneness, such as soft, medium, and hard-boiled. As the timer runs, the sand or liquid gradually moves from one chamber to another, showing the passage of time.

Adjustable Settings: Some models of the Wiltshire Manual Egg Timer allow you to adjust the timer to your preferred level of egg doneness. This flexibility allows you to customize the cooking time based on personal preferences or recipe requirements.

Easy to Use: Using the egg timer is straightforward. Simply place the timer in the pot with the eggs while they cook, and monitor the movement of the sand or liquid to determine when the eggs are done to your liking. Once the desired level of doneness is reached, remove the eggs from the pot.

Compact and Portable: The egg timer is typically compact and lightweight, making it easy to store in a kitchen drawer or cupboard when not in use. Its portable design also allows you to take it with you when cooking eggs away from home, such as when camping or traveling.
