Our serials assistant reported this information: The magnetic strips work  just
fine, it's the label strip that goes on the
magnetic strip that doesn't always stick. This may be because the labels are
probably at least a decade old & losing their stickiness.
Tell Barbara Pope we use something called ProMag Magnetic strips w/adhesive.
They come in rolls. I don't know where we order them from because these
strips are probably also about a decade old and I have never ordered them. I
am sure you can get them at any office supply store/outlet/website.
