Swiss Peak gifts are of the highest quality but the design must also be outstanding. This 500ml double wall, vacuum insulated stainless steel flask is certainly no exception. With its flowing curved body and efficient push button operation, beverages can't help but taste better when poured from a Swiss Peak Vacuum Flask. It will keep drinks cold for 24 hours or hot for up to 12 hours. The flask laser engraves to a stainless steel finish and is BPA free. It is beautifully presented in a Swiss Peak gift box and handwashing is recommended.
