Set of 4 clip-type red LED lights, perfect for DIY projects. I recreated the instrument called the Laser Harp, used by Susumu Hirasawa. It's unused. You can play your favorite Sunphling sounds using a PC and software. The Laser Harp's laser beams aren't visible without smoke, like from a humidifier, so a reasonably priced humidifier is also included. For those who love electronic instruments. For musicians who are fans of Susumu Hirasawa (*^^*) Although it's new, please understand that it's a handmade item before bidding. Thank you very much m(_ _)m - Type: Clip-type LED lights - Quantity: Set of 4 - Color: Red - Connection method: Wire connection - Application: For DIY projects Thank you for looking.
