Re: What costs?
Even a simple change to a mold for plastics costs $10K or more for the new mold to be manufactured.
Takes a lot of cartridges to amortize that cost without a substantial increase in the cost of the product contained in that new design container.
Gillette was successful with the model because the blades they manufactured were the same over ~decades~ of time, they didn't try to bring out a "new and improved" blade every six months to a year.
