Good luck, GJ, but another difference is Stone Island is an established and respected brand.
If these poles are the same, fair enough. But I get the feeling you've missed the boat, Gardiners and the like were there before you. If you'd sourced a Gardiners pole abroad at those prices you're onto a winner.
You're selling a cashmere jumper, really, not a Stone Island cashmere jumper. It matters to some. And remember, China isn't Italy.
Again, if you'd found a viable alternative to carbon fibre then you might be onto something.
