Access controller. I am selling it because I no longer need it. It has few scratches and is in good condition. I have pets, so there may be some odors. Price reduction is possible. If you wish to lower the price, please use the price negotiation button. Please note that the person who purchases the item will be given priority, even during price negotiations. I do not offer exclusive listings. Instant purchase is OK. Please feel free to ask if you have any questions. ^_^
