Custom Packaging

Well, Hasbro has no copyright over the character that I am planning on making, nor am I selling it on the Bay.

Just keep in mind this is verge of crossing the line. Hasbro announced just last month that they were cool with loose customs, but were adamant about if you are packaging them as actual manufacturer made, even as a custom even the package and title, branding, etc. are all trademarked and owned with potential legal ramifications.

This was a result of the Ebay auctions for the carded custom Gijoe figures.
Im certain most toy companies feel the same way.

I guess you could try heating the plastic and and mash it into the shape you want, then use cold water to make it hold. It's not like it matter show badly you mangle it, it's see-through so you don't see it anyway

I am going to try to take the packaging from a figure(DCUC packaging, specifically) and make it so it is the packaging for a custom figure, as if the figure was made by an actual toy company and had it's own packaging already.

I assume for the paper parts, you would have to scan them into a computer and mess with them to get it to be the right sizes and pictures and everything.

But how would you make the plastic that the figure is held in place with? There is the possibility of using the original thing from the base figure(if you have it), but that might not work if the piece was from a different size box(TB ML specifically) or it might not work if it would be a pose that the character wouldn't be in.

So basically, what would you do for the plastic that holds the figure in position?

That's a loaded question, what are you trying to do?
