Need advice ! ^^

Soo my mum had this blush thing but it finished so she gave the box to me (cuz its gorjus). I use it as a mirror thing now but I've been wanting to using the slot things for something else too. Fyi I don't have much makeup, and i don't rly wanna cut down my stuff and melt it in there. Some ideas on what I can put there will be great, doesn't HAVE to be makeup either. Ty ^{^}
