Photos 3 and later are taken from Rakuten. I purchased these new, but I ended up with more than I needed, so I am selling them. There are 5 packs of 5, for a total of 25, but it is also possible to sell just one pack of 5. If you would like to do so, please contact me in the comments. Also, please feel free to contact me if you have any questions. As of now (12/27), the lowest price on Amazon is 763 yen for a pack of 5, so I am selling a pack of 5 for 750 yen, including shipping. This listing is for 5 sets, so it will be 3750 yen including shipping. Thank you for your consideration.
