•【Handmade Craftsmanship】I t should be noted that as the products are handmade, the shells are made by Walnut wood, it cannot be guaranteed that each product is exactly the same. The bottle will not be filled with water because the pressure inside the bottle has to be relieved, and there will be some air bubbles inside the bottle.
•【Usage Notes】 In freezing temperatures, the water in the bottle may freeze. Place the product in a warm area and wait for it to thaw before use. Air bubbles are designed to prevent freezing issues. If flickering occurs due to low outlet voltage, use a power adapter to resolve it.
