Okay, I never predicted that there would be such interest in this ink and I'm a bit unprepared Before PenShow I made around 280-290 ml of each color, some of the ink was already sold there, and now the rest of it is already reserved. So I'm sorry that everyone else would have to wait a bit for this ink - production takes some time, at average 5-7 weeks I can speed up the process but 3-4 weeks, but this is a minimum to settle down the ink.
I never made a chart with colors because I constantly add new ones and sometimes change existing ones - creating inks is a hobby for me and earlier sales were made either on pen meetings or after sample exchange. During this Easter I will try to prepare charts with inks - there is around 34 of them.
Like with all waterproof or water resistant inks proper pen hygiene is a must - do not mix this ink with residues of older ink and everything is going to be alright. I also do not recommend using those inks with celuloid pens - dyes used in those inks have high affinity to cellulose, I never spotted any problems, but there should be no reason to risk.
I have two types of bottles 60 ml for (5,8€/8$) and 30 ml (3,1€/4,3$) - I ship using standard service by Poczta Polska (quite reliable) inside Europe for shipping it would be around 6$ for up to four 60 ml bottles, to North America it would be up to 8$ for four 60 ml bottles.
Because of coming Easter I will be absent for few days - I will post more information about inks on Wednesday (23.04). I hope that I gave answers for most of the questions for now.
