Drop n Tell monitors (Near Butler)

17 use-once drop-n-tell monitors. Self adhesive. Mechanical, not electrical. Place on a package/box/whatever that you are shipping/moving and this can indicate if it was dropped while on the way. These are all 25G, which I am told is a fairly normal sensitivity setting. Comes with adhesive notices you can also place to caution folks that the thing is being monitored for drops. (These do not alert you when something is dropped at the time of the dropping, they provide an indication that something has been dropped at the receiving end.)We used some for a recent move, don't need the rest.
