Stack nicely -good for legos, Lincoln logs and cars. I use mine for laundry soap so it wont get hard, dried out and lose it s surfactant properties. I also use them for powdered milk. They make great containers for small pasta, beans, or just about anything you can think to put in them. Contact paper can also be used.
Zip lock bags Use for storing coupons, crayons, q-tips, makeup and cotton balls for travel.
You can also punch holes in the edge of a heavy duty zip lock bag to put in binder to keep stamps or bills in. The reason I like these is because of their wide mouth. We use a combination of wet and dried ingredients in this type of jar like ranch dressing, dried rice, barley and tea bags. Large Popcorn Tins One of my personal favorites. You know, the kind that are so prevalent at Christmas time.
