Triple chrome plating means it has been given electroplated with chromium 3 times instead of the usual single plate, resulting in a chrome layer approx. 3 times as thick. Much more durable and covers the base metal better to give a deeper finish.
Good video👍😊 The triple coating is also for those with nickel allergies etc too. I've got one and an Infinity CRP they're great. The Infinity CRP can be a bit trickier to take apart especially with the 0.15 set up, but not as fiddly as certain Iwatas.
