I bought this new a few months ago to make cosplay masks and didn't realize that the form space was too small for the larger masks I was making.  i ended up building my own vacuum former at a larger scale and a separate heat box.  This one is great, I bought a lot of extra sheets (clear and white) to practice with.  I could make smaller masks with it, but I build my new box to be flexible to do both large and small.  I only used this a handful of times and like I said it worked perfectly.  The first two times was just to learn how to use it and the next three times was when I realized it was too small for my application.  I considered keeping it, but it's just taking up space and will probably never get used.  I have receipts of where I bought it and how much I paid for everything if needed.  Please email with any questions.  I priced this to sell.  Free shipping to contiguous US addresses only.  Sorry HI and AK and no international shipping.  43 white sheets and 42 clear sheets.
