Stay refreshed throughout the day with this BUILT set that includes a double-walled water bottle and a travel mug. In collaboration with V&A, it features a recreation of an unfinished watercolour, painted in 1918 by C.F.A. Voysey - an architect-designer renowned for producing exciting wallpaper prints, textile designs and graphics. The stainless steel bottle is as robust and practical as it is pretty. Produced from top-quality, highly durable materials, its the perfect companion for commuters, gym fans, hikers and birdwatchers. Thanks to clever double-walled insulation, and the latest Perfect Seal technology, the vacuum flask is entirely leak-proof and will preserve the temperature of your drinks without affecting the outer surface thats in contact with your hand. Tea, coffee and soups will stay warm and delicious for up to 6 hours without burning your fingers, whilst iced tea, water, and other cold drinks remain refreshingly cool for up to 24 hours. The travel mug features a vacuum-insulated body that is made of 18/8 stainless steel which insulates cold drinks for up to 24 hours and hot for up to 6 hours, keeping them as fresh as any "just-purchased" option. The double wall also means the exterior will stay at a comfortable temperature to hold, while a sturdy Tritan lid easily slides open and closed for one-handed drinking. It has a capacity of 590 ml (20 fl oz).
