My systainer labels have been doing fine except for the C12 systainer label which has gotten chewed up. I have a bunch of other storage boxes and cases which have no labels. However, I decided that writing labels on sticky tape, systainers, boxes, etc. was for the birds. Besides being messy (my handwriting is horrible) it's either TOO permanent or comes off quickly.
To remedy this, I got a "Brady ID Pal" (http://www.bradyid.com/idpal/Specifications.html) at Home Despot about a month ago. The ID Pal is a little pricey, but the labels use thermal transfer technology not ink jet, so the text is pretty permanent. The labels come in a little cassette which pops in and out quickly to change label height or material. You can print multiple font sizes, multiple lines on a single label, and the labels come in sizes .375", .5" and .75". The labels come in white vinyl, clear and white polyester, and white nylon cloth. I only have the white vinyl and it sticks to all the surfaces I've tried so far. For real stickiness, the nylon cloth labels are supposed to be better (but I don't have any).
The ID Pal works well and provides a quick way to create a clear, relatively permanent label. If it get's damaged, I can print out a new one in a minute or so. I'm not sure if it would be everyone's cup of tea, but it works for me.

Dan.
