These are good for holding bags of beans & such. They stack nicely so they save space un the cabinets or pantry. They are airtight & keep mice out. I use them for lots of things. The 30oz are tall enough to hold spaghetti. The 220z & 15oz ones are also good for holding starch, baking soda & baking powder. There are many uses for these like noodles, dog treats, instant potatoes, & many other things. I recommend them because they are airtight & they easily start on top of eachother.
