Igloo 6 lbs Performance Freezer Block Blue - 1 Pack

This large modular ice block is next-level with a unique brick shape designed thicker to hold more of our supercharged freezing gel with a relatively small surface area, which means it keeps your large cooler ice-cold way longer and the refreshments inside enjoyably frosty. And, equally as important, you won’t end up with waterlogged sandwiches.
