Grove item idea: Ice pack

I have an idea for a grove item! Maybe this would cost like 3 GC!

Ice pack:

Item look: three pieces of ice, a lil melted

Ability: Use it on up to 40 uses of food to make it last maybe 18 days, or 24 days (2x the normal amount or 3x the normal amount)

This would work well for those who are selling a lot in bulk, or plan on going afk for a few days and come back to a hungry pack!

Any more ideas to this?? Hopefully this suggestion doesn't already exist.

I like this idea, I recommend posting it to game development though!
