Ume(Plum)Snack Pickled Plum and Kelp Dried Plum

Both are healthy snacks at around 20 calories each.

They're super sour but totally addictive!

This one's FamilyMart exclusive (just has their logo), but you can find it at supermarkets too!

I think it's Japanese soul food—might be an acquired taste, but I absolutely love it.
