I like their green and red, the rest not so much.I’ve continued to use my Kawecos (2 different flavors of Ice Sport and 1 Sport) every day. This was prompted a bit by the fact that several years ago, I bought something like 6 small packs of Kaweco cartridges of different color inks. Kaweco ink is very well behaved, though nothing special. I have now used all but my 6 pack of black ink, so I’m going into the home stretch to finish up the stock.
