This is a great value replacement hook set. Although the hooks are small, they have excellent hooking performance, and the offset design makes it difficult for fish to escape. We jointly purchased these commercial fishing hooks with fishermen and use them ourselves, but we can't keep up with the consumption, so we are listing them. Suitable for various deep-sea fish. Please refer to the second image for hook dimensions. Hooks: Konawa Tai Needle, size 13 Leader: Carbon nylon, size 6, 70cm Proven use for: Horsehead fish, scorpionfish, thornyhead, various grouper, rockfish, sea bream, black cod, etc. Ideal for fishing at depths of 100-200m. Made by a fishing-loving old man, so there may be some variations. Please understand this before purchasing.
