ShaftRing Long (Silver) 's Japan Review

Used to prevent flight dropout
It is good to buy a spare

I have used many types of flights and this is the item that can lock the strongest flights.

I'm a tool enthusiast, but I've never seen this for sale w
I honestly don't know how it works, but I want one!
I want to use this to tighten the shaft and make it harder to remove the flight.
The style of not drilling a hole is very attractive.

The shaft ring prevents the shaft and flight from coming off, which reduces stress.

I have not actually used it, but it looks easy to use!
