These were collected in a park in Aichi Prefecture, with the left being from 2022 and the right from 2023. The one in the middle of molting is from 2022. There are 48 molted shells each, but there may be some miscounts. The number of this year's shells may increase before the item is listed. Some have missing legs, so please understand this. I may need a little time to ship depending on the timing, so please feel free to comment. Additional: Molted shells +10
