Studio oh insulated water bottles are beautifully crafted of boa-free stainless steel and feature fresh, full-color artwork from some of America's most exciting young artists. Their double-walled construction and unique vacuum seal keep drinks cold for 24 hours and hot for 12 with no exterior condensation; the opening is large enough for ice cubes yet small enough for drip-free sipping. And, they even fit comfortably in a standard-size cup holder for on-the-go travel ease. Studio oh insulated stainless steel water bottles measure 10" tall and hold 25oz./750 ml. The passionate and creative designers at Studio oh believe that products should not only be relevant to the needs of today's consumers but also should be environmentally responsible, infused with energy, elevated design, richly-saturated colors and fine craftsmanship.
