Hexagon wrench set I have from a long time ago, I did not break, but because I can not store it compactly like this product, I bought a new one at this time. Anyway, I was surprised that KTC made available at this price. For my use, this product, no dissatisfaction.
The impression of using was fitted perfectly in the hexagonal hole and it was used and it was very easy to use without slipping. This size was adopted for use in a narrow place. I could use even this length, but I think that it was even easier to use if the shorter length was about 10 mm shorter. I hope it will increase the lineup if possible.
