I purchased this item 3 or 4 years ago, but I don't think I'll be using it. It's new and unused, but please understand that some time has passed since its purchase. According to ChatGPT, Heattech should be fine for several years. I'm sorry, but I'm not offering discounts or holds. If there are no buyers, I will periodically review the price. Please understand that this item has been handled by a person once. If you have any questions or would like additional images, please comment. Instant purchase is OK. Basically, it will be shipped via Mercari delivery, in anonymous, simple packaging. (Yuyu or Rakuraku) I do not have any pets or smoke.
