Duke is a sophisticated 800 ml single-wall stainless steel bottle with a contoured body for a comfortable grip. It has a secure screw-on polypropylene lid featuring a push-button straw that locks away when not in use to keep it clean. An integrated carry handle is built into the lid for convenience. The matte painted finish gives a refined appearance, and the BPA-free construction ensures safe use. Branding is available via pad print or laser engraving, with engraving producing a shiny steel finish. Supplied loose packed, the bottle should be hand washed to maintain decoration.
