Stay Cool Anywhere with the 600ml Reusable Ice Crystal Pack
Keep your food, drinks, and essentials perfectly chilled wherever you go.

Why You'll Love This Ice Pack
- Long-Lasting Cold Retention: Dry ice crystal particles absorb water and expand, delivering powerful, sustained cooling that outperforms traditional gel packs.
- Reusable & Eco-Friendly: Add water just once — the crystals expand and lock in cold. Rinse, refreeze, and repeat endlessly for a sustainable alternative to disposable ice.
- Leakproof HDPE Shell: The durable, food-safe HDPE high-density polyethylene casing keeps everything sealed tight, so your bag and food stay dry.
- Compact & Portable: At just 18.5 × 12 × 3.5 cm (7.28 × 4.72 × 1.38 in), it fits neatly into lunch bags, cooler boxes, camping packs, and insulated totes.
- Incredibly Versatile: Perfect for food chilling, beverage cooling, breast milk preservation, air-conditioning fan enhancement, outdoor barbecues, and refrigerated transport.
- Easy to Use: Fill with water (leave space for expansion), freeze for 2–4 hours, then drop into your cooler or lunch bag — it's that simple.

Frequently Asked Questions
Q: How do I activate the reusable ice crystal pack for the first time?
A: Simply open the pack and add water — leave some space inside as the dry crystal particles will expand as they absorb moisture. Seal the lid, then place the pack in your freezer for 2–4 hours before use. You only need to add water once; after that, just refreeze between uses.
Q: Is the 600ml ice crystal pack leakproof and safe for food storage?
A: Yes! The shell is made from food-safe HDPE high-density polyethylene, which is durable and leakproof. The sealed design ensures your cooler bag, lunch box, or food items stay completely dry while the pack keeps everything chilled.
Q: How long does this reusable freezer block stay cold?
A: Cooling duration depends on ambient temperature and insulation, but the ice crystal formula is designed to retain cold significantly longer than standard gel packs. For best results, pair it with a well-insulated cooler bag or lunch box.
Q: Can I use this ice pack for camping and outdoor activities?
A: Absolutely! Its compact size (18.5 × 12 × 3.5 cm) and leakproof build make it ideal for camping, picnics, barbecues, road trips, and outdoor sports. It fits easily into most cooler bags and portable lunch containers.
