Multiple pieces have defects where the top layer is not properly glued to second, showing discoloration patterns, rendering the artistic portion of an otherwise great puzzle idea, utterly useless. While I initially believed pieces could have simply been exposed to heat during transit, I can now confirm this happened during the production (cut) phase as those patterns are all continuous over two connected pieces. I reached the company through they customer support on their website, where I left my email and mentioned proof pictures I could send, and did not have an answer (6 days later as of today). Because of the fact that the company did not follow up and that their quality control allowed this item to be shipped, I can't recommend this company. I also note that a few pieces are contorted. While this is not a major issue, at that price, I expected perfect.

The box came with multiple items and not enough care to box em in there, so the box came a little dinged up but it looks fine inside I guess.

Good Birthday Present

I'm definitely looking forward to solving it! I think I'm the only person my girlfriend could have bought this for that would really enjoy solving it. It is very intriguing though!
