The body is bright Kobalt blue so you can quickly and easily identify the metric set of hex keys. A quick-release switch is located on each side of the case to close the corresponding tools in one simple motion. All associated hex keys fold neatly into the case for neat storage and easy transportation. Meets or exceeds ANSI specifications. Hassle-free lifetime guarantee.
