Due to thickness, it will be shipped flattened. Made of soft silicone. Size: M Authentic product. I think it was around 3,000-3,500 yen. For my 6kg dachshund. I bought it to prevent him from eating things off the ground, but I didn't really use it, so I'm selling it. By the way, the size was fine. It's clean, but it's not new and has been stored at home. Please refrain from purchasing if you are concerned about minor details. Only those who can transact smoothly and pleasantly. Inspected. For your dog's safety, please do not leave them unattended while using it and use it correctly. Pay attention to drinking water, panting (mouth breathing), etc.
