CoreFlow vs LuxeSip/LuxeFlow

"Premium does not have to mean premium-priced. It has to mean no shortcuts."
The CoreFlow is the entry point to HYV — fewer accessories, same standards. 18/8 SS 304 steel, double-wall vacuum insulation, and a build quality that does not reflect its price.
Less accessories. Same standards.
750ml of 18/8 SS 304 food-grade stainless steel in a rubberised matte exterior. The CoreFlow is proof that price is not the reason to use lower-grade steel. HYV does not.
