Introducing an exceptional, double-walled thermos cup that's leakproof and made of recycled stainless steel. The cup features a plastic interior wall, a screw-on lid, and a click-opening function. It also sports an eye-catching 3D geometric diamond pattern. It's designed with a non-slip base and is RCS-certified. The cup contains 42% total recycled material and has a capacity of 250 ml. What's noteworthy is that stainless steel can be recycled numerous times without losing its quality. By using recycled stainless steel, we minimize the need for new raw materials and thereby reduce energy consumption, water use, and CO2 emissions. This cup is a sustainable option. The products are supplied in sets, with each set packaged individually in a box.
