Purchased in March 2017. It has been stored unopened at home since purchase. The box was opened once to take out the candy inside. The box shows some deterioration, but the item itself shows no signs of degradation. Although unopened, the tape has deteriorated over time due to long-term storage. The inner case is also crushed. Please check the images and consider before purchasing. If you are concerned, please refrain from purchasing.
