【Harrows】has1633 Extra short (13.0mm) 's Japan Review

It is nylon, but not particularly fragile.
The use of rings is a good idea as it eliminates the tendency for flights to come off.
The color selection is great, and the cost performance is excellent.

Extra short nylon shaft that is the most normal.
The shaft part is shiny.
The part that holds the flight has a rough matte finish
The shaft ring has a rough matte finish to prevent the shaft ring from slipping off.
The material is soft and the part that holds the flight is easy to break, so it is better to drill a ring hole in the flight
It is better to fix it firmly.

It's simple and comes with a ring, so it's a great value.
