Rapid 10-minute heating and hydrogen production to improve water quality High Borosilicate Glass: Lead-free, transparent, safe, and healthy, crafted using traditional techniques for excellent production. Imported SPE ion membrane for high hydrogen concentration Wire-drawing stainless steel fuselage: Fashionable, easy to clean, and wear-resistant Special Reminder: When you receive the product, when using the cleaning cup for the first time, be sure to pay attention to a row of 4 holes "anion release hole" above the cup body, and do not let water enter to prevent the digital circuit control from malfunctioning. If water gets in, try to throw the water out with moderate force (pay attention to safety, do not crush the cup), and put it in a cool and ventilated place for about a week to air dry for "self-healing".
