The perfect fit for your handbag or backpack, the thermos features a smart silicone straw in the lid that makes it easy for children to drink from. The bottle was designed by Tobias Jacobsen and has been adorned with the iconic Arne Jacobsen typeset, the well-known font that was originally conceived in 1937. The thermos keeps warm drinks warm for up to twelve hours and cold ones cool for up to a day.
