Alaskey® Giant Ice Block Mold with Lid (2-Pack) - Shape 12 lbs Ice Bricks - Professional Silicone Mold for Crafting Giant Ice Cubes, Ideal for Revitalizing Ice Baths, or Coolers Accessories...

Works great. Bought two with lids. have a large Yeti cooler. Keeps me from buying blocks as long as I keep building and rotating! Easy to use and convenient. Pay for themselves quickly. I recommend them.

These are good quality. All of these at this size are way too expensive for what they are. But if you are dead set on getting ice blocks of this size, then these are the best price and quality.

These work great

Works great to form a block of ice.

fast Shipping and so far great buy!

Solid sturdy material to make the giant ice cubes! 5 lbs is a big piece of ice!

Very well made and durable. I have used this to fill several ice blocks and even with the ice "bulging" during the freezing process, no damage to the containers. Lids fit securely enough to water from spilling when carrying from sink to freezer. Getting ice out is very easy if you rinse briefly with some water.My only recommendation would be to add a visual "FILL LINE" as a reference when filling with water since filling to the brim can result in spills or lid popping off during freezing.I originally got these to mass-freeze ice blocks for a cold plunge tub, so the size of the ice blocks has been great.

Works perfectly
