This is a set of '5' CR425 (BR425 compatible) batteries! Please note that the packaging may vary. As a fishing enthusiast myself, I also use these batteries. Domestic batteries are expensive (over 150 yen each...), so I think these reasonably priced compatible batteries are sufficient. Thanks to them, I no longer have to be stingy with batteries, and I can turn on my "electric float" from the early evening. I don't miss the fishing opportunities. They are essential items for "night fishing"! Specifications: Pin-type lithium battery Voltage: 3V Dimensions: Approximately Φ4 x 25mm For different quantities, etc., click here: ↓↓↓ #LithiumBatteryIzuOkappari
