These are hooking barbs for Ayu rolling (korogashi) fishing. All of them are single-hook barbs. They are primarily for rolling, but because they have round ears, they can also be used as a teaser for friend fishing (tomo-zuri). * Fox type, size 9: 390 pieces (80 pieces x 4, 70 pieces x 1) * Yajima type, size 9: 60 pieces * Yajima type, size 10: 123 pieces * Both Fox and Yajima types have brown, round ears. ⚠ The Fox type is new and unused. The Yajima type is from disassembled, unused rigs that I made myself.
