This is a listing for six 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. There are six colors of rollers: 1: Green, 2: Dark Green, 3: Red, 4: Blue, 5: White, 6: Black Please specify the number after purchase.
