I've been keeping this item, which I won in a gacha (capsule toy machine?) at a venue booth several years ago, unused. ※ The signature was already on it when I received it, so I didn't ask for it. The package says "limited edition," and I can't find it online, so I think this gold color was exclusive to the venue's gacha. This is the "RIELL" 6th model by Mayu Shimizu. The main grip area with a gentle taper incorporates a combination of wing, shark, and ring cuts to optimize grip.
