This is a set of replacement filters and the main unit for the ELFIN FOUNTAIN E1+ automatic water fountain. The replacement filters come in two boxes of 4, for a total of 8 filters. The main unit was used for a little over a month, but my cat didn't like it and wouldn't drink from it, so I'm selling it. Overall, it's clean, but I couldn't remove the water stains on the tray, so I've marked the product condition as "slightly scratched or dirty." I will ship it in the same packaging as when it was purchased. 【Brand】ELFIN FOUNTAIN 【Category】Automatic Water Fountain, Replacement Filters 【Color】Clear, White 【Contents】Automatic Water Fountain Main Unit x 1, Replacement Filters (4 per box) x 2, Power Adapter x 1 Thank you.
