MISSION DARTS MISSION GRIPLOCK SHAFT Red Tweenie 's Japan Review

I think the quality is slightly lower than Pro Grip shafts because there are often burrs in the flight insertion area, but I personally use them because they are not bothersome to me.
I would recommend it to el-style users as well, as it fits champagne rings and shell locks perfectly.
It is a steel dart, but it has not broken yet after more than a month of use.
It is nylon, so I think it is indeed easy to break with soft darts.
