Why You'll Love It

• 🧊 Space-Saving Collapsible Design: Folds down from a 5.1-inch depth to just a 2-inch flat profile — saving precious freezer and cabinet space when not in use. No more bulky, hard-to-store ice molds cluttering your kitchen.
• ❄️ Massive 8-Pound Ice Blocks (9.5" × 5.8"): Giant blocks have minimal surface area compared to their volume, so they melt far more slowly than standard ice cubes. Keep your cold plunge tub or camping cooler at freezing temperatures for days, not hours.
• 💪 5mm Thick Food-Grade Silicone: Heavy-duty walls stay structurally stable when filled with water, yet remain flexible enough to peel back effortlessly for a one-second ice release — no cracking, no warm-water rinsing required.
• 🛡️ Smart Lid + MAX Fill Line: The included tight-fitting lid prevents spills on the way to the freezer, blocks food odors, and lets you stack multiple molds. The clearly marked MAX fill line prevents ice expansion damage — no more guesswork.
• 💰 Reusable & Economical: Stop spending money on daily bags of store-bought ice. Fill it, freeze it, and you're ready to plunge. Pro Tip: Place the mold in the freezer first, then fill with a pitcher for zero spills.

Frequently Asked Questions

Q: How long does it take to freeze a full ice block in this silicone ice mold?

A: Freezing time depends on your freezer's temperature setting. For a full 8-pound ice block, we recommend allowing 18–24 hours at a standard freezer temperature of 0°F (-18°C). For best results, ensure the freezer is not overloaded and the mold is placed on a flat, level surface.

Q: Is the silicone food-grade and safe for use in cold plunge tubs and coolers?

A: Yes! This ice block mold is made from certified food-grade silicone and carries CE/EU, LFGB, SGS, and FCM certifications. It contains no BPA or other high-concern chemicals, making it completely safe for producing ice blocks used in cold plunge tubs, beverage coolers, and food storage chests.

Q: How do I release the giant ice block without it cracking?

A: One of the biggest advantages of this collapsible silicone mold is its effortless one-second release. Simply peel back the flexible silicone edges from around the frozen block and it pops right out — no cracking, no running warm water over it, and no waiting. The 5mm thick walls provide stability while freezing but remain pliable enough to flex easily when you're ready to remove the ice.

Q: Can I stack multiple molds on top of each other in the freezer?

A: Absolutely. The included tight-fitting lid is designed to support stacking. You can place another mold or other freezer items directly on top of the lid once it's secured, making the most efficient use of your freezer space. The collapsible design also means you can store multiple flat molds in a fraction of the space of traditional rigid ice molds.
