Joanne,
Just seen your post and sorry to hear that you have had an issue with some of our labels. Our standard labels are Pharmaceutical Grade PU which are tear resistant and you should not have experienced any tearing issues. This is the first report we have heard of this nature and we will happily replace any labels that are not up to standard; if you could kindly let me know which school/schools this relates to I will get some replacements made and have them dropped off.
Joe
