The internet is full of generic Philips drivers sold as JIS at a premium. As far as I can tell, this is the real deal. Tested a couple of JIS (JIS B1012, slightly recessed) cap screws between these and some quality Philips drivers and the difference was day and night. The Philips drivers are loose and can wobble quite a bit. These JIS drivers "almost snap in" and sit tight and flat. I disassembled the carburetors on my '82 Honda bike last weekend and these riders even removed the bolts that have been removed by Philips riders in the past without breaking a sweat. They're a bit pricey, but if you can spend a little time working with Japanese-made devices, treat yourself. 100% worth pulling out the cleaned heads with a vise and a dremel.
