These are empty baby food jars with printed labels. Due to the nature of the jars, the lids do not completely seal once opened. They have all been washed with detergent and dried, but there may be some minor scratches or odors. Please be aware of this. I believe there is no residue, but jars that contained strongly colored baby food may have some color transfer on the underside of the lid. I have 24 jars available, and I have listed them on a separate page for those who wish to purchase them in bulk.
