We need to label our containers that we use for our surgical instrument cleaning, and need to re-label them every time the chemicals are changed (at least daily, and sometimes more often). These labels are perfect! They stay on the containers (which are both plastic and metal), but come off easily with no residue. Re-labelling has never been easier! We also print the labels with the chemical information ahead of time, and will often print hundreds at a time. Even when printing large quantities, there is never any "shadows" on the labels, as will sometimes happen with off-brand labels. The labels never peel off or stick in the printer. We have had some less-than-desireable experiences with Non-Avery labels..........we have learned our lesson, and will never use another brand!!!!!
