I did my part and bought two sumi art kits over the past two years.
Maybe their problem is that the glue is too good, and the bar of ‘ink’ lasts too long. Both of mine are hardly worn down..
I’m not sure how you go about ensuring your survival making this sort of product though. I suppose cutting costs is your only hope.
It is probably akin to trying to save the punch-card or typewriter industry. I’d hate to see this one go though, but I’m sure there will be demand in the future, and the people that continue to supply it will be the ones that survive. I wonder if they could expand the number of markets in which they engage in business.
