I still use the Caboodles makeup case my sister bought me when I was 11, in the late '80s. it was the first thing she ever bought for me. She had gone away to boarding school and we went from sharing a bedroom to becoming pen pals. We've been long distance sisters since then because after high school she went on to other schools and only came back home to visit. Back then, I looked forward to slumber parties and overnight road trips just so I could take my black, white and hot pink Caboodles case along. In those days it housed, like, every flavor of Bonne Bell lip gloss, clear mascara (yes clear, because my mom didn't let me start wearing mascara until I was in 9th grade, but even then it was brown--might as well have been clear), and brown lip liner. I used it all through college too. So I'm attached to it for sentimental reasons and because it's awesome. No reason to replace it. I've tried to upgrade to one of those slick, fancy train cases I see everywhere, but this old plastic thing holds SO much more than the newer ones. Over 20 years with the same makeup case...has to be a record.
Bonus Confession: I just parted with the deep lavender lip pencil and gloss duo that I used on my wedding day almost 9 years ago. I haven't used it in years. It's just that every time I cleaned out my stash I held on to it for sentimental reasons, I guess. Finally got rid of it a few days ago. There was something fuzzy growing under the plastic cap on the pencil end, so it was time.
