I use them for everything except plants
I have a pink VW Bug that I use to hold my bookmarks and I have a giant pair of red lips that I use to hold all of my pens.
I remember my childhood best friend had these at her house, her mother was a painter and rode her bike around town in heeled garden clogs, she wore lipstick everyday and it was always all over her toothbrush. coming from a tupperware home, these jars felt special, and cold leftovers tasted better eaten straight out of them. I don’t currently own any but I think I’ll buy a set when I’m done moving around.
