Electric fishing floats. Two out of the four National floats are missing their tops, but floats #3 and #2 are compatible. Fujito-ki floats are #1, Large-Large, and Medium. All the lights work. These are electric floats that are easily lost when fishing at night, such as around tetrapods and other obstacles. Having spares gives you peace of mind. *Please note that only one battery will be included, so please purchase with this in mind. I'm selling them cheap, so please consider purchasing them!
