I know that this is a box o' C., but, let me tell you, you haven't lived until you've washed dog pee off of:
a laprade style seatpost
a tube of grease
2 brake levers
a bag of brake pads
a bell, and
a rubber mallet

My dog had an accident in the house, conveniently all over a cardboard box o' parts I had sitting on the floor.
Don't worry, none of these items will be going in the Box when I sent it out.
