This is a set of two USB controllers made by ELECOM. * JC-U2912FRD (Red/Black) * JC-U3312SSVD (Silver/Black) The red and black one has some color fading and shows signs of use. The silver and black one has little wear and is in good condition. Both have been connected to a PC and their basic functions have been confirmed. Please consider that both are used items stored at home. I will ship within 24 hours of purchase via Yu-Yu Mercari delivery. Thank you for your consideration.
