Surely it can be used on a rainy day, but it is useful. On the other hand, there is a time when it is not so good at sunny weather and it breaks too much. It is fine if it is a smooth surface, but it seems that it will take some time in a rough place.

Eight out of ten pieces broke when breaking open. It is the frequency of use whether to use once a year, so I will not return it .... Even when I ordered a thin oil stone before, it was also uneven.

It is useful because it is mainly used in rainy weather or in damp places. It is regrettable that red chalk was not sold.
