I believe we have achieved all that with our cap and plug kits, which are the best on the internet. Let me point out some of the things that are important to us.
1. The little insert in the cap of the flat face and metric caps, has to be integrated into the cap. In other words, it will not fall out. We have worked with our suppliers to insure this step for all our caps.
2. The compartmented boxes are a translucent polypropylene we get from Flambeau Inc. and we feel are the highest quality available.
3. We laser engrave the size on the JIC and FLAT FACE kits for easy identification. Everything is done in house.
4. We include a paper insert in the lid of the box that shows all the specifications of the caps and plugs and even the torque recommendations of each size.
