Besides juice, attys, cartos, and bottles.
-Batteries, extra. I keep plenty of IMRs and keep them in rotation and number each with a permanent marker. The battery cases that you get from the battery vendors are very nice to help with organizing them.
-2 chargers. In case one goes "boom" I also have the corresponding car charger for each of those chargers, in case the power goes out or if I am going to be on the road for extended times.
-extra favorite drip tips. I can't seem to wrap my lips around anything but a pawn tip now, so if it breaks, I got backup
-noalox from home depot. I just like keeping extra, besides what Rob gave me, because I bathe the REOs a lot.
-q-tips, cosmetic flat pads, to wipe and clean the REOs with alcohol
-bent paper clips, to pull out tops of cartos and I use it to straighten unruly cartos
I know some of items may seem silly but I truly can't live with my grands without these items.
