Review on Enhance Engine Performance with Stanley Proto J000K Spark Plug Gap Gauge Set: A Comprehensive Review and Buying Guide by Eric Nelso

Despite the proto stamp, this is not a Stanley tool. There is no Stanley mark anywhere on the tool and this tool is cheap, poor quality and well below Stanley Proto quality standards. The design of this tool is such that you can't even use a finger lock to push out the sensor wires as the cheap plastic holders don't go into the clearly intended "push" range. In addition, at least three sensor wires were clearly deformed when they were received, so that they stuck to the housing even when using a different tool (!) to push out the sensor wires. , described as "Stanley Proto", is most likely a fake.
