Purchased on Amazon. I bought this when I first got my dog because I was worried, but I didn't need it, so I'm selling it. Batteries were not included, but I will include them. Box and instruction manual are included. The effect is unknown, so if you are considering purchasing on Amazon or Rakuten, why not give it a try? I will sell it to those who understand that the effect is unknown. Thank you. The images from the 5th one onwards are borrowed from the product pages on Rakuten and Amazon.
