【Harrows】has1621 Medium (33.0mm) White 's Japan Review

It is nylon, but not particularly fragile.
The use of rings is a good idea, as it eliminates the tendency for the flights to come off.
It is the best cosmetic product I have ever used.

Light.

If you are going to use a flight other than Fit, this would be the one.
Raro is also good, but the cost performance is very different.
You can buy 2 or 3 sets for the same price.
I like the ring that comes with it.

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

I bought it because of its cosmetic quality. The champagne ring and shell lock work fine. It is not as good as the el shaft in terms of hardness to pull off, but on the other hand, when I grouped, I sometimes got into the target place thanks to the flight coming off.
I recommend it if you don't mind the difficulty of inserting the flight or the lack of a flight guard.
