[misc] my sister keeps using my expensive face products - cheap beauty lock box?

Beauty Tips For Body Care
Basically it all says it in the title. I keep asking her not to and she still does. I know she’s using them because I’ll position them a certain way and the next day it’s moved (I know kinda creepy lol but I need to know).Is there a lock box for face products I can buy? Something under 30 dollars would be great! Thank you
