most likely .... perhaps ;-)
would be a good idea to use some additional means of preventing drying.
the staedtler pens are "dry proof" meaning as long as some liquid
ink is in the pen the tip won't dry. it will thicken a bit. they say 2
weeks
open i think and it still must go.

oh, yes, i see you already understand they are dry proof... sorry for that.
I think it is alcohol based. it is solved by alcohol, and it is no stronger
solvent (plastic survives). It also has a light alcohol smell.
the labels on the refill are highly flammable and irritant.
Alcohol does not carry irritant normally, so it could be another solvent.
