The PhiBottle is made of borosilicate glass and can bear the -20℃ to 150 ℃ temperature difference.
With the rope handle the bottle is portable and it fits through its 7cm diameter in almost every car holder. Another bottle cap without a rope handle is also included. The silicone sleeve protects you from hot drinks.
We suggest hand wash only to protect the logo. Remove the silicone before washing.
