What can I fit in Kanken side pockets??🫠

I guess I can successfully fit a skinny energy drink in my kanken mini😭😭 I drink alani but I’m sure u can also fit a red bull too. My friend likes to put pens and pencils there and my dad suggested putting chargers. I js don’t have that much trust in putting lil loose things on the sides.. what if they slip out!! Anyways I found what works for me LOL 😭 #kanken #kankenmini #bag #backpack #travelbag #energy #suggestions #letschat
