Arguably, one of titanium's best traits is its durability. Quartz best trait is, arguably, its flavor. So why shouldn't a hybrid nail utilize the best that both materials have to offer? So for our latest adaptation of the hybrid nail, our goal was to create the most durable quartz/titanium hybrid nail on the market. Our updated quartz dish (QX2) has twice the wall thickness, twice the dish volume, and is both taller and wider than its V1 predecessor. On top of being larger, it's durability is significantly increased thanks to a new titanium Quartz Shield (QS) which accompanies it (available separately - see QS listing). Both the quartz and titanium pieces are American made and precision machined to fit together.
