I own and love the Dragon Double-Walled Tea Tumbler, but unfortunately it doesn't have a built-in tea strainer. The cool new Golden Dragon Bone China Tea Tumbler, on the other hand, not only includes a removable stainless steel tea infuser, but it's also made from fine bone china as well. This attractive 8oz tea tumbler is the perfect ancient vessel for taking your favorite teas on the go and features a twist-on lid that keeps tea sealed in and warm. I think I'm going to have to upgrade.
