Why brilliatech do clay block in one grade of clay for sponge block (clay block)? because we keep the quality clay for sponges; all clay lock with sponge. the sponges are also most same funcation, just differnet color and thick. and all clay blocks are same using by hand. so we try to one clay for clay blocks. we support to change surface texture of the clay on the sponges. such as wave shape, net shape, and pionts shape.....
