The set of 46 elements is packaged in a practical case. The case allows for safe storage, each element has its place, so finding the right compass or key will not be a problem and everything will not get lost.
Replacing parts in hard-to-reach places often causes a lot of problems and access is impossible using a regular wrench, so in this case, extensions and couplings will be perfect.
All elements are made of chrome vanadium steel, which makes them very durable.
