Thank you for viewing. This is a TWINBIRD ZABADY waterproof DVD remote control, model VD-J719-7. Operation has been confirmed. It has been disinfected with disinfectant wipes. It has been stored in a dark place with little use, so I don't think there is any discoloration. It uses two AAA batteries, but batteries are not included. Thank you for your understanding. * It will be wrapped in bubble wrap and sent via Rakuraku Mercari delivery [anonymous delivery].
