Why You'll Love It

• High-Grade HDPE Shell: The leakproof outer casing is made from durable HDPE (high-density polyethylene), built to withstand repeated freezing and thawing cycles without cracking or leaking.
• Dry Ice Crystal Technology: Contains coarse dry ice crystal particles with excellent expansion properties, delivering a powerful and long-lasting cold storage effect that outperforms standard gel packs.
• Add Water Once, Reuse Forever: Just add water to activate the crystals — they expand as they absorb moisture and freeze solid. No need to refill between uses; simply re-freeze before each outing.
• Fast Freeze Turnaround: Place the filled pack in your freezer for just 2–4 hours and it's ready to go, keeping your cooler bag, lunch box, or portable cooler at the ideal temperature for hours.

How to Use

1. Open the lid and add water — do not fill completely; leave space for expansion as crystals absorb water and freeze.
2. Close the lid securely and place in the freezer for approximately 2–4 hours.
3. Once fully frozen, transfer the pack directly into your cooler bag, lunch box, or portable cooler.
4. After use, clean with neutral detergent and water, then re-freeze for next time.

Safety Precautions

• Do not open the lid to consume the ice crystal contents — not for ingestion.
• Keep away from fire or high-temperature objects.
• Clean only with neutral detergent and water.
• If crystal liquid overflows during expansion, clean and continue to use normally.

Frequently Asked Questions

Q: How do I activate the reusable ice crystal freeze pack for the first time?

A: Simply open the lid and pour water into the pack — but don't fill it to the brim. The dry ice crystal particles inside will absorb the water and expand as they freeze, so you need to leave some room. Seal the lid and freeze for 2–4 hours. You only need to add water this one time; after that, just re-freeze before each use.

Q: Is this freeze pack safe for use with food and breast milk?

A: Yes. The outer shell is made from food-contact-safe HDPE (high-density polyethylene) and is completely leakproof, making it suitable for direct contact with food containers, lunch bags, and breast milk storage. Note: the crystal contents inside are not for consumption — do not open the lid to drink them.

Q: How long does this ice pack keep food cold, and how many times can it be reused?

A: The pack offers a strong and long-lasting cold storage effect, keeping contents cold for several hours depending on ambient temperature. The great news is it can be reused indefinitely — simply clean it, pop it back in the freezer, and it's ready for your next outing. No need to add water again after the initial activation.
