The collar size tag was irritating my neck, so I cut it off. I believe it's a size S. I haven't worn it very much. The fourth picture, which shows the tag, is the closest to the actual color. It doesn't seem to have much pilling. Because it's bulky, I will use either Yu-Packet Plus from Yu-Yu Mercari Bin or Takkyubin Compact from Rakuraku Mercari Bin. It depends on whether I have a box at home. If it fits, I'll use Nekopos. If you purchase it with other items, I will ship it via Takkyubin from Rakuraku Mercari Bin.
