【harrows】SUPERGRIP ULTRA FLIGHT AQUA 3501 's Japan Review

I bought this as a gift for a friend. I didn't really like foldable flights, but I had no choice but to buy this one because the only flight my friend liked was a foldable one. I think the design is really cool. However, as for functionality, the foldable design does not maintain a precise 90-degree angle, and it is thin, so I feel that it wears out (scratches) easily.
