The balls and the ball holder is made of stainless steel. Works perfectly for me and looks like it will last long. **Q: Does it go on forever? Or like an hour?** A: An hour! You're an optimist. This thing is horrible. It goes for about 15 seconds. I'm returning it. I remember these things from way back when and they would go for much longer. I'd gladly spend twice as much for one that was decent, but this is a waste of time. **Q: what are the stings made of?** A: They appear to be nylon fishing line **Q: I am purchasing these for a hotel and need 420 units - what is availability?** A: As of 7 14 2023, we have over 700 pieces in stock ready to ship via Amazon. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Beautiful scientific tool *by J***N on 1 November 2025* Loved this stress relief tool ### ⭐ Garbage.
