【UNICORN】PURIST SEIGO ASADA DNA 90% TUNGSTEN SOFT 24G No.23251 's Japan Review

First of all, it is too heavy, so it is not suitable for ordinary people. It is for advanced users who can use the weight to throw well.

Also, as mentioned by other users, UNICORN's hole drilling accuracy is rough. Some shafts cannot be mounted because the screw holes are too tight.
Even if you forcefully attach the shaft, if the shaft breaks, you will not be able to take out the broken shaft because of the tight screw holes.
