World has bee small.
I received another pots mailed from overseas yesterday. It is quite short time from the order to the receiving.
Since the largest size of G-pot was 6, I tried to order similar to the one and size 7.
I found a pot called Noah-pot in the website of another supplier, which was similar to G-pot.
I repotted an Ariocarpus retusus v major into a Noah-pot, size 7 yesterday afternoon.
