Our Chalk Jar Large Flat Storage Jars are simple ceramic white jars, each painted with a square of textured blackboard paint. These jars are perfect for storing everything from last night's leftovers to the crayons scattered all over the kids rooms. They provide a neat and tidy way to organize and store items, while retaining a uniform style. And as your storage and cooking needs change, the jars can be wiped clean and re-labeled. Dishwasher and microwave safe
