2 Pack of 2 Quart Double Wall Pet Bowls. Our Pets Durapet double wall stainless steel dog bowls have so many benefits compared to traditional dog bowls made of plastic or ceramic. Stainless steel bowls are easy to clean, 100% recyclable, and contain no harmful chemicals. Our double wall dog dowls take the typical single wall stainless steel pet bowl and make it even better. The thick steel material keeps the bowls super durable and will help to keep your pet's water cooler. The air between the two lays of steel insulate the bowl by forcing heat to transfer through the air before reaching the content inside of the bowl. You can think our bowl just like your double wall stainless steel tumbler you use for water or coffee. They are similar in the designed where they keep hot drinks hot and cold drinks cold. Since our bowls are so durable they are great for indoor/outdoor use and traveling. The anti-slip rubber base design will help to keep the bowl from sliding around like your pet is enjoying their meal or to for keeping your floors scratch less.
