This is the second time I’ve offered speedy-cut (speed ball) from America. It is my favorite rubber block. Really as smooth as a butter. The only thing is it is too soft to carve details such as letters. So for most of  the order-made stamp cases I will use another rubber-SEED made by Japan.
This speedy-cut  is 6 3/4 x 11, the biggest one. I think this time I will try to carve some plate in a post card size, not only for small stamps. The weather is just beautiful, I have to do more sketch in my city.
