This is a Bluetooth 4.2 speaker designed with the Tokyo Yakult Swallows' mascot, Tsubakuro! It's a compact and adorable Tsubakuro that makes a statement! How about adding it to your room as an interior decoration? *Bluetooth Version: Bluetooth 4.2 *Size: W80 x H100 x D100mm *Battery Capacity: 500mAh *Communication Distance: Approximately 10m *I haven't had a chance to use it, so it's still unopened. I've been storing (displaying) it on a bookshelf. Thank you for looking!!
