Covered cat litter box with lid and carbon filter

Selling a covered litter box with a lid and a carbon filter in the top. It's been used for around six months by one cat, and I have cleaned it regularly, so it's in very good condition. The plastic is still smooth, there are no cracks, and the filter has been replaced once. It's a good size for a medium-sized cat. I'm based in Sukhumvit, Bangkok, near Asok BTS. I can meet at the station on weekday evenings or on weekends. Message me in the app and I'll get back to you the same day.
