If you are concerned about the mishandling of your cups and having them resist to the tribulations of everyday life, or wish to be able to propose a good quality cup to more inexperienced hands that may frown at holding a handleless cup for the first time, this is the cup for you. The first thing you will notice when holding this cup is its weight and thickness. It is thicker to provide added insulation for sensitive hands as well as resist the abuses of everyday life. I guess that by now you understand how it got its name... Further than these functional features, this is a cup offers all the refinement necessary to showcase any of your good teas! It offers a good volume and shape and is a pleasure to handle. One other little detail, when tilted sideways as it would be the case when knocked over, the cup will always return to its standing position. It is that well balanced. Handcrafted in Taiwan according to our design and specifications.
