This is product number 03 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 create a small space by interpreting the functional part of the handle as a curved wall and roof, and to become the morphological point of the mug. You can place simple items on the top of the handle. 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 clay containing paper fibers, so you can see a unique surface texture that is rougher than other existing mugs.
