The glass water bottles are designed to provide a pleasant drinking experience. The threading is located on the inside of the bottle neck, offering you a smooth surface for drinking. The lid is coated with high-quality stainless steel both inside and out, ensuring that your water does not come into contact with plastic. The bottles feature a non-slip silicone sleeve and a convenient carrying strap. The almond-colored sleeve is made from a combination of wood fiber and TPE for a unique texture.
