Timeless Swiss Peak design is very evident in this smart 350ml vacuum cup. Its double wall vacuum insulation will keep drinks hot or cold for longer and the tough powder coating laser engraves to shiny steel finish. This BPA-free cup has a secure screw on transparent Tritan lid with a leak resistant flip closure that locks open when in use. It is beautifully presented in a Swiss Peak gift box with an information leaflet included. This product is not dishwasher safe and handwashing is recommended.
