Well, if they are popular in the places you mention, I suggest you make a quick bang and get out of the business. Build it up fast and sell the whole thing to a larger company. The product seems to have "novelty" written all over it. I do not buy into the idea that it will have the lasting power of a fork. And even if it does last longer than a quick fad, I can't imagine a two person enterprise competing with a major manufacturer when your patent expires. (that's no slam on you. I'm only speaking to the idea of how cheaply plastic pieces are manufactured and sold by overseas corporations)
But, I can see marketing them to restaurants. Maybe Hooters. Not sure of the marketing campaign for them...maybe...Girls don't like messy boys...or...At Hooter's, you won't get sticky fingers from your food.
I doubt individuals would buy boxes of these. It doesn't seem to be something one would need at home.
And, at a restaurant, as someone said, after you use it, you're not likely to stick it in your pocket and walk out with it. Also, trying to get these on retail shelves would be a tough job for a small company. You're probably smart sticking to the food business and bulk buyers like a chain restaurant.
I'm originally from CNY, and we're pretty serious about our wings. Hard to believe Trongs would take off in that area. But, hey, I'm no marketing guru for sure!
Good luck Dan.
Oh, PS - the only bad thing, now you're without an excuse when you miss a call!
