I had a bag of all my yoyos (like 10 or so) some lube and silicone and pliers and who knows what else and was fine. They checked the pliers to see that’s what they were but that was it. You’ll be fine.
I took all these yoyos half way across the world with me, no problem
They grinned at the Trainwreck though, probs because of the Spikes, but I just told them “im going to a yoyo contest” and they were fine with it.
