Box 4 flat ratchet keys TNT from 9mm to 27mm

Here is the box of TNT flat keys. This box very well studied includes 4 flat keys from 9mm to 27mm. But how did they do you tell me?

These keys are adjustable very easily thanks to a Phillips screwdriver allowing to adjust the key to the desired size. In addition they are ratchet keys thanks to a spring system very well studied. This avoids tedious handling when dismounting your 2 wheels. The advantage with this kind of box is that you can disassemble your 2 wheels without needing a complete toolbox. Just take these 4 keys and a Phillips screwdriver and you can almost disassemble your 2 wheels in full.
