The Twist Straw Cap for the TKWide stainless steel vacuum flasks from Klean Kanteen has an integrated straw and a large swivel handle made of stainless steel. The straw can be folded out and folded in again by twisting. The bottle does not have to be tilted to drink, so nothing spills. The plastic material is BPA-free, odorless, tasteless, light to clean and dishwasher-safe.
