Hahaha - This made me chuckle. I bought a little container that holds 24 lipsticks/eyeliners/pens/whatever and just out of curiosity, decided to put lipsticks only in it. Shocked to discover that in my various handbags, drawers, etc., I had about 40, gathered over decades - many hardly used because the shade didn’t suit or the texture was wrong. So I gave away or ditched all of those and kept a couple in my handbag and bedroom, with just four or five in the makeup container, including precious ones that can be used only with a lip brush as they are down to the insides of their containers! I reckon even these few will last me the rest of my life, no matter how long that will be. (I’m 73)
