【Material Matters】A bowl is just a bowl, right? Sadly, that's not the case. Most pet food bowls are made from stainless steel, plastic, ceramic. Plastic is the worst option which contain chemicals that could disrupt an animals hormonal balance. Apart from that, plastic accumulates deep scratches that harbor insanitary things and can be hard to clean. Ceramic is heavier and far less durable. One drop or bang can chip, crack, or shatter your ceramic bowl, making it no longer safe for use..【Rust Resistant & Rubber Bottom】Made from genuine stainless steel. If properly cared for, your stainless steel dog bowl will last for years. Regular metal bowls that try to pass themselves off as stainless steel when they are actually regular steel (carbon steel) will rust in no time. The added slip resistant rubber rim on the bottom prevent the bowl from sliding around and reduce noises while your dog eats..【Easy to Clean & Dishwasher Safe】Dog bowls made out of stainless steel can easily be cleaned with mild dish soap and warm water. In addition, they are also dishwasher safe, making for easy cleanup. After manufacture, each batch of bowls is tested for lead, mercury, and cadmium by an independent lab. These bowls are so safe that they're fit for human use, too!.【Stackable Design for Easy Storage or Travel】With a considerate and convenient design, these bowls stack easily inside one another for easy storage or travel.
