Might I kindly ask what company do you work for? Through your various posts you speak as though you work in this industry? Freelance work? - where can I see the work you have done which has been produced? I'm just curious - thanks!
Currently I do not work because I am disabled. I do some freelance work from time time. Primarily with fashion. I do know the fabric may have cost a pretty penny especially in the states. I remember a nice foil fabric I had printed in black with gold foil cost $5000 for a bolt of 8 yards. It was something I photoshop and sent a file with detailed notes. In Asia it is cheeper but you take a risk especially in shipping of it being damaged. I have done a a project with a friend years ago that he had a metal mold made there not cheap. And I know clear resin can be tricky to both dye and seperate from a mold because of it's tendacy to adhere itself to the mold. Even with a release agent. So I do know it did cost a great deal to make this.
However if a spandex suit would have been made and a simpler design could have been done on the construct. It could have made the cost lower. I'm assuming the lantern was a 2 part mold. Can't tell if handle is metal if not that is another 2 part to seperate to retrieve it and the bottom would be a one part mold possibly like you would to make a sea shell.
The lantern would be unavoidable cost but the rest could have been made cheaper.
