Semi-permeable design - The top blue part is impermeable canvas and the black part is permeable nylon mesh. This semi-permeable construction can be collapsed together with the water tail, and the water amount can be freely controlled. Durable soft mesh - The soft nylon net with full-surface stitching protects the fish mouth and helps prevent bruising. Suitable for carp in pond environments, during tank changes, isolation, and similar tasks. Strong compressive resistance - The handle is made of aluminum alloy, providing high compressive strength and durability; not easy to break. Suitable for large fish up to 60 cm. Convenient and practical - The handle is made of engineering ABS plastic, with high hardness, non-slip and durable. A non-slip opening on the tail allows hanging and convenient storage. Use scenarios - In-pond carp handling: Use during catch and transfer of carp up to 60 cm, with controlled water management to reduce stress. - Tank changes and isolation: Use the soft mesh and full stitching to move or isolate fish with minimized mouth injury. - Storage and transport: Use the tail opening to hang the tool for easy storage when not in use.
