Hi Helene, Geoffrey here, co-founder of Bubble Poi. Thank you for the honest feedback, and I'm sorry the construction didn't match what you expected.
You're right that we use industrial-grade nylon ties to attach the rings to the body of the poi. This is intentional: we tested a dozen alternatives (metal clips, sewn loops, glued joints, welded plastic) and nylon ties were by far the strongest, safest and longest-lasting solution for the tension bubble poi generate when spinning at full speed. They hold hundreds of pounds of pull without failing, they don't rust, and they're easy to replace at home if ever needed. Every poi kit in the flow arts community uses similar attachment methods for the same reasons.
That said, we'll take your feedback and make the construction even more visible on our product page so future customers know exactly what they're getting.
And beyond the ties, I really hope you get a chance to give the poi a proper spin. Once you follow our video tutorials and get your first massive bubble trails flowing through the air, I think you'll fall in love with the practice. Our customers around the world are creating truly magical moments with these kits, and I'd love for you to experience that too. We're a small team and every customer matters to us!
Geoffrey
