Butter keeper.
Lasts for weeks at room temperature.

We leave our butter out in the pantry, and put our bananas in the refrigerator.
Mrs. Alaska just bought 6.5 pounds of bananas at our local Giant Eagle for 99 cents, we ate two and the rest went into the fridge.
Yea, the skins will turn black, but we can eat two a day for more than 10 days and they will be fine.
The butter has never gone rancid, but we've only had 63 years of experience, so the jury is still out...
