This is product number 02 in a series inspired by Brutalism, an architectural style that exposes the building's functions and facilities without hiding them and uses rough exposed concrete. It was designed to become the morphological point of the mug by interpreting the functional part of the handle as the wall and roof. It is designed to cover the oval-shaped body and thin walls so that you can enjoy the interesting structure of the mug in a variety of ways. Among the hand building techniques, coiling and pinching techniques are used, so the appearance of the unevenness is slightly different for each product, and the thickness is thin, so it can be used lightly. Instead of the exposed concrete used in construction, it is made of relatively rough clay containing grog, giving it a rougher but unique surface texture than other existing mugs.
