It all depends what I am doing, favorite inks for various techniques or styles.
Just checked my "go to" Baggie I travel with, to see what I did have there. Several Ranger Archival colors (blacks & browns), Memento's, Versa Mark. For colors I have only two I heas for deepening on purpose.... Either my new SU inks or my TH Distress Inks.
I have a bunch of ins in various brands.... They rarely see the light of day.
