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 previously sold Uki Top and are now offering the newly completed NEW 39.FACTORY Uki Top. Here are the features of the 3rd generation Uki Top: ⭐︎ Following the 2nd generation Uki Top, it is compatible with not only the lithium battery BR435/2B size but also the shorter BR425/2B size. ⭐︎ A hard pipe has been added to the Uki Top body, allowing the unstable electrodes to be fixed, preventing problems such as breaking or bending the electrodes. ( ^ω^ ) Along with this, it also prevents lighting failures due to poor contact, a feature inherited from the 2nd generation. The major feature of the 3rd generation Uki Top is the addition of a special cap 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 Uki Top (3rd Generation) https://youtu.be/cU_YFs-FhDw?si=B6FUkiTWGllcEssM The light color of this product is yellow. 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 electric floats failing to light up due to poor contact, which would break them. I would then have to buy new ones at a fishing tackle store for around 1000 yen for an electric float or around 500 yen for a Uki Top. (/ _ ; ) I hated this cycle, and I decided to make them by hand for those who have had the same experience and feel the same way. We would be happy if you would try it once. Thank you very much m(_ _)m Also, please refrain from purchasing if you are hesitant, as these are handmade.
