Silicone is excellent in durability, heat resistance, impact resistance, and chemical resistance, making it hygienic and resistant to dirt. The diameter of the water bottle bottom is generally compatible with 8.8-9.2cm. Not only does it protect the water bottle, but the elasticity of the silicone also prevents scratches on tables, even if children carelessly place the bottle down. It can also be used for repair if the bottom is already damaged. As long as the size is right, it can be used not only for general water bottle manufacturers' products but also for plastic bottles and my bottles. ■ Product Details Size: 9cm diameter, 4.5cm height (for 0.8, 1, and 1.5 liter bottles) Weight: 45g/piece Quantity: Set of 2 Color: Black 【Note】Changes to the delivery method cannot be accommodated.
