This is a long-distance casting float. It is approximately 30cm long. It says "ENTO No. 3," but it's unclear if this refers to buoyancy. The manufacturer is likely Kotobukiya. I found this while organizing old fishing tackle. Overall, there is a lot of dirt, paint chipping, and scratches. Also, as it has been stored for a long time, deterioration over time is expected. Please purchase if you understand that this is a used item. If you have any questions about the condition, please comment. I will respond with additional photos, etc. ENTO Cage fishing Chum cage Top cage Three-point fishing
