Me too. The nutella jar is such an awkward and messy shape to get nutella out off, especially as it gets emptier and emptier. I would prefer it in a regular wide-mouth jar if that were available.
Even better, give me nutella in caulk gun form. No wastage, accuracy in application to your toast and you just need to wipe the nozzle to keep it clean. No knife or spoon to clean either. There are tons of condiments I would prefer in caulk gun form. For jams and jellies, there would be no excess air that result in spoilage from when bacteria and fungi get in the jar. Thicker jams with fruit chunks can just use a larger nozzle.
