Captain: Maxim from JNS is indeed a one man operation.
This quote is from the last e-mail I got from him:
"Because of my personal suff i mention in previous email , Unfortunately i have to close up for all shipments from yesterday to 2 January 2017
I will not be at my home this dates from 10 December to 2 January
I will also go for business trip to Sanjo Japan from 21 December to 2 January
I know it is long time but i have to do it !
So to make it up i make all that time discount in the store 15 % off, exc Shigefusa and Kato knives
You will get it automatically at checkout no code needed and i will ship it when i get home. "
I hope this explains some of the issues you have met.
I am sure you will be able to have a dialog with him by the time he is back.
Sorry, I just realised I answered in an old thread.
Hope you got your desired stones and items. If not, some are in stock, and again on sale
"personal suff" ... that is what happens at a German Weihnachtsmarkt
