By buying large quantities of blank inventory labels and offering just a few stock sizes, we are able to keep costs to a minimum without sacrificing quality. The silver mylar material that we use for some of our inventory labels is very durable. With the addition of the new aggressive adhesive material we are bridging the gap toward the much more expensive aluminum labels that most other companies sell. The inventory labels come with a permanent adhesive and should stay in place for many years to come. If someone wants to take them off, they will come off. With all the different surfaces that people stick them on it is impossible to predict how well the inventory labels will adhere.
