I haven’t read all the replies so apologize if there are some repeats. Some random things that come to mind include: large safety pins, extra lip balm, super glue, duct tape, eye glass repair kit, work and winter gloves, hair ties, hot pads, fly swatters, aluminum foil, dental floss, extra toothbrushes, dish soap, zip ties, binder clips, extra rope, a couple of sturdy buckets, hand lotion, extra can opener,
Much of this can be purchased at the dollar tree. Get it while you can and while it’s $1.00
If you are buying superglue, try and make it those "single serving sizes" because once you open it superglue turns into a superdud fairly quickly because it dries out.
