An innovative way to brew tea to go, Pào Tea Mug from Puresigns combines great style and functionality. Unscrew the lid and add your loose tea to the compartment tucked into the lid. Add boiling water, turn upside down, and start brewing. When the tea is as you like it, switch the filter flap and you're ready to drink a hot, fresh-brewed drink. The unique lid locks to secure it while you're on the go, and the double wall insulated stainless steel keeps your tea piping hot.
