These nets are designed especially for handling small fish in ponds, tanks or large aquariums. Each frame and handle is all aluminum and securely attached. These nets have a protector across the face and a sleeve over the junction of the net frame and handle to protect all edges from coming into contact with fish. Net bags are poly mesh. A-11 and A-12 have 1/4" black mesh. A-13 and A-14 have 1/8″ white mesh.
