It was not until 1904 that researchers prepared alloys that would become what is now considered stainless steel. Today, there are over 150 different grades of stainless steel and, due to many of its intrinsic properties, it has become the ideal base material for a range of commercial applications, including stainless steel drinkware. The broader category of drinkware falls within the top selling categories of promotional products annually because it is widely used, thus making your brand widely seen. And with the added advantages of stainless steel - resistant to stain, rust and corrosion, low maintenance and low cost - stainless steel drinkware can garner an even greater reception from recipients. While this awesome material boasts its own natural luster, and does not need to be painted, our selection includes options with metallic color finishes for complete customization.
