As the title says, these are homemade. I got hooked on one-tenya fishing a few years ago and learned to make my own. I caught a lot of fish with these, and I think they'll work just as well with shrimp attached. The green color is because it seemed to get a good reaction from the sea bream. I used to fish around Hitachi, Ibaraki Prefecture. Store-bought ones can be expensive, and I didn't have to worry so much about losing these to snags. I've lost interest now, so if you'd like them, please take them. Please refrain from purchasing if you are overly concerned about minor imperfections. Thank you for your understanding. I have: 5-go (5号) x 2, 6-go (6号) x 1, 7-go (7号) x 3, 8-go (8号) x 12, 10-go (10号) x 7, 12-go (12号) x 8, 15-go (15号) x 5. That's a total of 38 pieces. Thank you.
