Set of 10 Inner diameter: 4mm Length: 9-10cm Because the inner diameter is wider than commercially available pipe tenbins, even if the line is pulled out, the leader will come out properly, and the function of the guided tenbin will not be lost. ※ Similar items at fishing tackle stores cost around 1500 yen for 10, and the inner diameter is narrow, so the leader cannot come out completely. Line ⭐︎Use PE line 5-8 and leader ⭐︎Use 20, 24, and 30 size sinkers Material ⭐︎Urethane tube ⭐︎NT Power Swivel I use these homemade tenbins every time, and I have no line troubles and have been getting good results! I always use 30-50 size sinkers. I have never had a swivel come out during my use. Thank you. The price has been slightly increased due to the rising cost of materials. #Okinawa #UchikomiFishing (Surf Casting) #BukkomiFishing (Bottom Fishing) #Taman (Giant Trevally) #Gara (Grouper) #Meebai (Grouper) #GT (Giant Trevally)
