Simple! This was an idea for handling ice cream cones or cup.
We built some prototypes to test at some favorite stands.
We cut a slab of thick clear plastic and drilled various sized holes.
We hung electric ceramic heaters above a wooden form for shape.
A brochure explained the idea and suggested hole sizes.
This ideas too simple. Too cheap. Small market. Not worth pursuing.
But, some did like the "Cone Caddy" ... we traded for ice cream.
