I am selling these because a family member used them, but no longer does. White stones: 147 (see second photo) Black stones: 165 (see third and fourth photos) Material: Unknown (definitely cheap) Of the black stones, 9 have particularly noticeable scratches or cracks (see fourth photo). Of the white stones, 5 have particularly noticeable scratches or cracks (see seventh photo). In addition to the 5 mentioned above, many of the white stones are deformed and partially flat. I will sell these to someone who understands that they are used items.
