I have never used the high-fine seal, so I don’t know much about it, but it seems to be specially used to seal seals with many tiny details. It seems to be more delicate. As for the water drop stamp pad, which has a special shape, it is very convenient to color the small parts of the stamp at its tip. The small drop-shaped ink pad is very convenient when you want a seal to be locally different colors. As for its use, it mainly depends on the characteristics of each brand's series. Water drop ink pads are produced by Japan's TSUKINEKO, while cat-eye ink pads with the same purpose belong to Color Box's "CHALK" series.
