The gap measuring tool arrived well packed, also it has a small plastic bag, to store the tool, protecting it from direct humidity or dust. It has a nice range of blades to work with, the gap size is well readable at normal light. You can disassamble the tool, so you can add 2-3 blades on top of each other if you need to measure a slightly bigger gap, than the latgest blade in the pack allows you to do so.
