Thank you for viewing! This is a brand new, unopened pet outfit. It's made of thin polyester. Smooth and highly breathable. Perfect for summer to autumn. Also good for preventing hair loss. Although it's new and unopened, due to being an imported product, some items may be opened once for inspection before shipping. Basically, it will be shipped in its original packaging. Please refer to the photos for sizing. Even for small dogs, there are individual differences, so please measure your pet before purchasing to ensure the size is correct. Cancellations are not accepted. If you purchase other pet outfits, you will receive a 50 yen discount from the second item. A 150 yen discount will be applied for the purchase of 3 items. Please contact me through the question function.
