Please note that this item will be shipped folded small in a Yu-Packet Post Mini envelope. If you are concerned about this, please refrain from purchasing. This is an iDog Marshmallow Knit. It has been worn once. There is also a yellow one, which has been worn 1-2 times. It's a DL size, but it stretches, so even dogs that usually wear XL size can wear it. Length is 37cm, chest circumference is about 23cm. I purchased it from the official website around October 2024, but it was only tried on and has been hand-washed. It is very stretchy and easy to put on and take off.
