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 negotiate a price reduction, 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. ^_^
