If you’re on a budget, ask your dad or grandpa for their old briefcase. If they don’t have one, goodwill for $5.
If you don’t need to transport them, I really think Drawers are my favorite way to store yoyos. I feel like cases just make it harder to play the collection frequently as I have to take the case out, leave it open/out, put the yoyo away, put the case away. With drawers, my throws are always, always within easy access or reach. If they’re not in a drawer then they’re on my desk and if I want to clean the desk up, I just fill my drawers.
