Anyway, I created a sheet of labels in Microsoft Word that will work for any of the following models of Avery label sheets (the sheets have 30 labels on each page and I only needed one page for the complete list):
Compatible Avery Label Products:
45366, 48266, 48366, 5029, 5268, 5366, 5368, 5378, 5566, 6505, 75366, 8066, 8478, 15266, 8590
Or you could just print them out on paper, cut them out and stick them inside the bags...whatever trips your switch.

You'll notice that the list only includes the items from Hardware Pack #1 and a few items from the Onyx Heated Bed Kit. Hardware Pack 2 and 3 contain fewer (or larger) parts and come nicely packaged and labeled so that additional labels aren't necessary.
Hope it comes in handy!
Here's the document:
