Most users are happy with the labels and can see them well enough, but we realize that is not the case for everyone and get this feedback regularly. We take all customer feedback seriously and have tested many solutions to make them more legible, including screen printing, printed overlays, and lasering through to a contrasting color. Given the compact nature of the kit and the space available for labeling, the current solution has been the best. If we made the kit much bigger with more space between the bits so there was more room for the labels we might be able to do something bigger and with more contrast. But at the current tiny size, lasering them is the most legible and long lasting solution.
