Thank you for viewing our product m(_ _)m This is 39.FACTORY o(^o^)o We value our customers' feedback and strive to provide, improve, and refine our products daily. ( ^ω^ ) We have discontinued the previous float top and are now offering the newly completed NEW 39.FACTORY float top. Here are the features of the 3rd generation float top: ⭐︎ Following the 2nd generation float top, it can use not only the lithium battery BR435/2B size but also the shorter BR425/2B. ⭐︎ By adding a hard pipe to the float top body, the unstable electrodes can now be fixed, preventing problems such as breaking or bending the electrodes. ( ^ω^ ) Along with this, we have also inherited from the 2nd generation the ability to prevent lighting problems due to poor contact. The major feature of the 3rd generation float top is that a special cap is attached to the LED light-emitting part, which protects the LED and improves visibility due to the increased length of the light-emitting part. Please take a look at the product introduction video on YouTube. ( ^ω^ ) Product Introduction (YouTube) NEW Float Top (3rd Generation) https://youtu.be/cU_YFs-FhDw?si=B6FUkiTWGllcEssM The light color of this product is rainbow. Please use Panasonic BR435/2B or BR425/2B batteries. When night fishing, I often experienced electric floats drifting out to sea for various reasons, or the electric floats failing to light up due to poor contact, which would break them. I would then have to buy new electric floats for around 1000 yen or float tops for around 500 yen at the fishing tackle store. (/ _ ; ) I hated that cycle, and I decided to make them by hand for those who have had the same experience and feel the same way. I would be happy if you could try it once. Thank you very much m(_ _)m Also, please refrain from purchasing if you are hesitant as it is handmade.
