I know probably very few of you if any still use film cameras. With the advent of digital cameras they are a lot easier and less expensive to use. But I know most if not all of you still have some of those film containers lying around. These containers are great for keeping track of small parts in your work area. Typically they are opaque so knowing which one to look in is always a pain in the ass. I took pictures of what was being stored inside and printed them out on small labels. I then affixed the label to the proper container and used a few pieces of clear tape over them so as not to ruin them with my greasy fingers when working on my bikes.
You can use any small container, even glass ones like baby food jars. I like these because they are small and durable. I also use these to carry small parts in my hydration pack like SRAM power links, misc. nuts or bolts, Marzocchi fork air fitting adapter, etc. In pack with fewer compartments these work great for keeping things organized.
