Ice Block Freezer Boards - Blue

Cooling duration varies based on ambient temperature and how often the cooler is opened, but typically lasts several hours (e.g., 4-6 hours) for everyday use in lunch bags.

No, hand washing is recommended. Dishwashers can be too harsh and may damage the casing or the cooling gel.

The ice blocks contain a non-toxic gel that freezes and provides a sustained cooling effect.

They are best suited for smaller to medium-sized bags and coolers due to their slim profile and 200ml capacity. For larger applications, multiple boards may be needed.

For a standard lunch bag, 1-2 blocks are usually sufficient. For larger bags or longer durations, consider using more blocks and pre-chilling the container.

No, these boards are designed to hold a specific non-toxic cooling gel. They are not intended for freezing other liquids.

Ensure your freezer temperature is set correctly (typically 0°F or -18°C) and that the boards are placed in an area of the freezer that maintains a consistent low temperature. Allow more freezing time.

Ensure the boards are fully frozen. For longer cooling, use more boards, pre-chill your cooler, and avoid opening it unnecessarily. Store the cooler out of direct sunlight.

If the casing is punctured or leaking, discontinue use immediately. Dispose of the damaged board safely and replace it.
