The brown one has been used for about 3 months and has bite marks from a dog. The ivory one is unused, but has been opened once. I'm selling these because I bought a new dog pen and the size doesn't fit. I originally bought them considering replacing the old ones. 500ml dog water dispenser, ivory and brown design. - Brand: Richell - Model Name: Water Dispenser - Size: 500ml - Intended Use: For dogs Thank you for looking.
