The problem with the current packaging of the marshmallows is that they are packed in a cheap plastic bag, which is not re-sealable. the solution to deal with this problem would be to have an easy to store package, which once opened, could be re-sealed or appear as its resealed so they stay fresh for a longer period of time.
The problem with the current packaging is that the plastic bag is very cheap
with no mechanism to seal the bag the leftover marshmallows become very sticky and gooey,
inedible which results in wastage of food and resources.
