Thank you for viewing! ^_^ This is a bamboo conical fishing trap with a wide opening, designed to efficiently catch eels. You place bait, such as small fish or earthworms, inside the trap, perhaps in a net. Once an eel enters, it cannot go back out due to the trap's design. This is a handmade item, crafted entirely from domestically sourced bamboo. It is new and unused. I've heard that eels are more likely to enter bamboo traps than plastic ones. Material: Bamboo - Type: Eel trap, trap, snare - Design: Conical Length: Approximately 67cm Circumference: Approximately 36cm Bottom Diameter: Approximately 12cm *Inspection by an amateur It's also perfect for interior decoration, and you could put LED lights inside. Please contact me if you wish to purchase multiple traps. This is a handmade item created by a former sashimono craftsman, but please understand that it is sold as-is, with no returns or claims. ^_^
