On the back side (near the neck), it's hard to tell if it's a stain or thinning of the fabric, even when held up to the light and touched, but there's an area of concern. I've included photos of all the areas I noticed, including this one, so please check them. This is a pre-owned item stored in a private home. I have checked it, but I cannot guarantee there are no oversights. Also, perceptions of wear and tear can vary from person to person, so please consider this a used item before making a decision. This item will be shipped via Yu-Yu Mercari便 or Raku-Raku Mercari便. I may change the shipping method without prior notice to the buyer.
