The transmitters were protected by cases, so they are in relatively good condition for their age. ※ The settings are B-band (800MHz band), so you can use them safely in Japan without a license. 【Shipping】 As these are precision instruments, we will take thorough measures against impact and ship via the anonymous Rakuraku Mercari service.
