Engel 5°F / -15°C Freezer Packs

Great for what it’s advertised for, but one gripe.

They work exactly as stated and stay cold for very long. The gripe I have is because I wasn’t sure what size I needed to lay it flat in my cooler for my lunches, but it stands on its side perfectly, just need to add how it’ll fit into each cooler in the description or pictures.

Works perfectly.

Difficult to Freeze

Freezer set to -5 F and they still are slushy inside.
