hey, i’ve been throwing for about 3 years now, and yet i still know nothing of yoyo bags :(. can anyone tell me what i should have inside one, what the actual bag should be, and if you have one post pics? this is an insane bump for me in yoyoing 
You should have yoyos in your yoyo bag.
I personally just use an adjustable coozie. I put one throw in, my yoyo gloves some string and then another one in. It seems to keep them from dinging and I’m always ready if humidity strikes back.
