Simple plastic box and a cleaning rod that came with a Taurus PT92 back in the day. I buy brass tips and nylon brushes as needed. Once in a while i will go to the beef jerky and tupperware emporium and buy a bag of precut patches and a couple pints of Hoppes #9 and I am good to go. Still working off the case of 12 bottles of CLP I bought from Odd Lots more than 20 years ago. I have lots of "kits" from when family members would give them to me for Christmas, but most of the hinges have broken and I just keep the better rods and tips in a box in the garage for when I need to replace one or need a new size.

Pride of place goes to a Dewey rod for my CZ .223, it hangs in the closet next to the safe. Nice piece of equipment.
