The Tea Tumbler: This double-wall glass bottle is a beautiful drink infuser and travel bottle. The built-in steel basket holds your tea (or coffee) for easy hot or cold brewing. This bottle comes with a neoprene carrying case and handle - offering sturdy protection and even better temperature insulation on the road. The tumbler fits inside a standard car cup holder, so no more worrying about spilling the tea. This glass bottle is also great for making and serving ginger or mint teas and fruit infused waters. The steel infuser is easily removable for cleaning, and the tumbler holds 400 mL (about 1.7 cups). INSTRUCTIONS: * Remove lid and infuser.
