I have issues with using the zip ties in corsets. First they hold in the heat as it is using polyester in your corset. This is fine if it is a short time use costume, but if you are using it for wear under multiple layers for a period correct look you will have heat issues. I have seen ladies go down in a 70F day with having used zip ties in their Elizabethan corset. It also likes to poke through worse than any steel I have used. I also have had the issue in a formal dress where they bent over and stayed that way the whole time. Even when you let it relax after an event (the formal) it will immediately recrimp to the bent form regardless of what you do in subsequent wears.

In regards to grommets in corsets, yes they work again if a costume, but if you use this for a firming corset (much less CW or Victorian) they will pull out and deform your look. I do however like the stainless steel washers to wrap and use and awl to create the hole for corsets. That is an awesome and strong tie. (Again depends on if it's a few time wear or your undergarment mainstay)

I agree, after researching cartridge pleats for the past 18 years, this is NOT a cartridge pleat.

I appreciate that you have done something cool, but really I agree with the other posters that it should be properly called.

I was happy to see the title as a costumer and thought, Oh cool, a way to show others. But frankly I cannot support the title with the descriptions. I'm sorry.
