Key Features

Long-Lasting Cooling: Coarse dry ice crystal particles expand on water absorption and freezing, delivering extended, consistent cold temperatures for your items.
Reusable & Efficient: Add water just once. Freeze for 2–4 hours before use. The ice crystal pack is ready to go and can be refrozen and reused repeatedly.
Versatile Use: Ideal for keeping food cold during transport, preserving breast milk, cooling air fan towers, outdoor barbecues, camping, road trips, and refrigerated delivery.
Food-Safe Construction: The shell is made from HDPE high-density polyethylene — food-contact safe and built to last.
Compact & Practical Size: At approximately 19 × 6 × 4 cm (7.4 × 2.3 × 1.5 inches), it fits easily in most lunch boxes, coolers, and small fan reservoirs.

Frequently Asked Questions

Q: How do I activate the ice crystal box for first use?

A: Simply open the lid and add water to the ice crystal box, making sure to leave some space for the crystals to expand as they absorb the water. Close the lid securely and place the box in your freezer for 2–4 hours before use. You only need to add water once — after that, just refreeze to reuse.

Q: Can the ice crystal box be used in air cooler or tower fan systems?

A: Yes! The ice crystal box is designed to fit into many air cooler fan reservoirs, providing extra cooling power on hot days. It's also excellent for lunch boxes, cooler bags, camping trips, and cold-chain food transport.

Q: Is the ice crystal box safe for food contact?

A: Absolutely. The outer shell is made from food-safe HDPE high-density polyethylene, making it safe for use alongside food, beverages, and breast milk storage. Do not open the lid to consume the contents.

Q: How long does the ice crystal box stay cold?

A: The dry ice crystal particles inside are engineered to provide extended, long-lasting cooling. The duration depends on ambient temperature and how often the cooler or bag is opened, but users typically experience several hours of effective cold retention per freeze cycle.
