Q: For the stackable jar.... Can they be used not stacked? I want to know if each jar has its own lid. I have seen stackable items where the lid of one jar is the bottom of another jar. Thank you!
Q: How heavy do you think this would be if each compartment was filled with a lip scrub?
Q: Is there a case to store the stackable round storage jars in. I purchased one at Michael's in the past?
