The Burnt Chef Project - Metal Thermal Travel Mug 450ml
Our Oregon 450ml double-walled, matt black stainless steel travel mug with coloured PP plastic interior. 
 
Save Money - All coffee outlets will fill your own cup for you instead of their disposable versions and some will even knock a bit off the price of your latte if you bring your own flask. And I believe you will be very proud of your contribution to environmental protection.
 
Safe Materials - Made of durable material. BPA & PVC free.
 
Heat-Proof - The silicone ring makes the mug much easier to hold, drink from and heat protection. Although when the hot liquid in the cup is above 80℃, the silicone ring will be cool.
