Using the rulers today, a student noticed some of the millimeter marks between each centermeter were missing. Between the odd numbered centimeters, there are only 8 dashes, not none - so a millimeter is missing. Horrible for science. If you are using to draw straight lines they might be fine. For science, they are pointless - I threw mine out today.
