Handy Size for snacks, or items that you don't have lots of. It also helps use the vertical space if you can go 3 high in a cabinet so it's sits on top of a 2.
Good for odd size items. I use one for pine nuts and one for Sweet Smoked Paprika. I use the diffuser for the paprika. If you have odd size spices or salad toppings like cranberries, this may be a good alternative for storing them. Its not too big, but still larger than the size recommended for spices by Zwilling. Probably would be a good alternative for a small "sugar bowl" used for coffee and tea service since you can remove the air from the container. It is a small utility container, so additional ideas will come to you when you use one for the first time.
