This is a listing for 20 self-made rollers for Japanese flying squid (Aori-ika) fishing using the Yaen technique. These are a thinner type than the ones I have listed separately. Because the rollers themselves have little wobble, they roll very well. A 1.0mm shaft fits perfectly. The rollers come in 6 colors: 1. Green, 2. Dark Green, 3. Red, 4. Blue, 5. White, 6. Black Please specify the number after purchase.
