We are pleased to announce that Kenwood's specific low-power transceiver "DEMITOSS UBZ-LU series" has been renewed! The new product uses ABS resin made from recycled materials for the main body and has reduced plastic materials in its packaging, making it an environmentally friendly model that takes SDGs into consideration. This contributes to a safer environment for future generations of our children. As before, it also features antibacterial and antiviral processing with the air catalyst "Cellfeel R." It provides peace of mind by protecting against various germs. This transceiver can be used without a license. Why not enjoy communication for work or at private events like camping?
