I've played with it a few times. It was stored in a dark place. This is a used item, so please refrain from purchasing if you are concerned. As this is an overseas product, there may be some imperfections in the manufacturing or some dust may be mixed in. It will be compressed for packaging, but it will return to its original shape, so please don't worry. Also, please understand that we cannot accept returns or provide guarantees for tears in the bag during shipping. MeloJoy Mochimochi Mochi
