Korean tea shaker

Not really an ingredient but a tool. Recently, I rented the two seasons of Grand Chef from Netflix (a soap opera drama about a Korean restaurant and it’s chefs…very nice for us Korean foodies as a lot of dishes are prepared on camera). In one scene, the girl gets this big plastic thermos looking thing, takes off the top (which is held together by four lock and lock looking clips, adds hot water and tea leaves, replaces the top, shakes, and then lifts up an opening on the top that has a built-in strainer that siphons out the leaves as she pours. Lovely little contraption, and I’d love to get my hands on one. Anyone seen something like this in their local Asian foodstore?
