Tampax boxes and the like, they are very unlikely to touch . Excellent hiding space
This is going to sound weird but I have to hide my stuff in my own home as it's been stolen before. I try to keep everything on me but I have to hide the rest in candy bar wrappers, Pringles cans stuff like that . It has worked for almost a year now.
OMG all I can think of is how many items would get randomly thrown out in my house if I did that. “Pringles can feels light, must be empty.” *someone chucks a diamond necklace in the trash*
