must-have ! Kuroki Goishi Ten Hon-Hama Goishi Blue Label Size 32

I am selling Kuroki Goishi Ten's Hon-Hama Goishi (Genuine Clam Shell Go Stones), Blue Label, size 32.

I purchased these from Maekawa Kaya Goban Ten (Kaya Go Board Store) 8 years ago. The current retail price is 52,000 yen.
I haven't used them much, and they are in attractive condition.
Kuroki Goishi Ten's Hon-Hama Goishi are classified into "Yuki-jirushi (Snow Mark)", "Hana-jirushi (Flower Mark)", and "Blue Label" based on their selection criteria. The selection criteria are shape, color, grain, and blemishes. Blue Label stones are those that did not meet the selection criteria for Yuki-jirushi or Hana-jirushi.
To the untrained eye, it's impossible to tell what didn't meet the criteria, but Yuki-jirushi size 32 stones, which have passed the selection criteria, retail for 336,000 yen.
Please see the Kuroki Goishi Ten website for more details.
The set includes 182 white Hon-Hama Goishi and 183 black Nachi-guro stones (photo 6).
The goban (go board) in photo 6 is not included.

Kuroki Goishi Ten's Hon-Hama Goishi are numbered to prove their authenticity. When exposed to a black light, the management number appears as shown in photo 8.
They appear bright blue in the photos, but are actually a pale purple. Some management numbers are clear, some are blurred, and some are not visible at whole.
I will include the pen-type black light used to take these photos as a bonus (photo 9).
A warranty card (photo 7) is included.
