Just in time for halloween! These are quart size mason jars with standard size necks (approx 7 inches tall), The jars have been tinted on the inside of bottle and have vinyl decorations on the outside. They have solar powered lid lights, which would cost you between $8 - $10 each, if just buying a lid light alone. No need to turn the light on and off!!!!!! You will also receive a solar powered lid light for each jar. The lid light fits any jar with a standard mason jar lid. The lid light is water resistant (but the inside of the jar is NOT) it has an automatic switch that lights when dark and turns off when light hits it. Replaceable and rechargeable battery, and bright LED are inside the lid. You can use these for Halloween and then store the jars and use the lid lights for other seasons. Do not put water in these jars. Not dishwasher safe. Do not use them as a food, candy or drink container. You can use them inside or out, but I think they charge best from outside light.
