3. Matryoshka 3-Piece Teaset for 2 by Sunart, Sold by Arigato Shop on Amazon
Take care with this kitchenware as it is made of ceramic, but the good thing is that the ceramic will also insulate your beverages and can stand high temperatures without warping in shape. Since the two cups can be stacked on top of each other on top of the teapot, there's a space saver aspect to the set as well.
