These are items I bought in the summer and didn't use. Brand new, unused. Set of 5 cooling packs How about these for sudden fevers during this season? It's a great chance because they're hard to find in stores this time of year!!!! About shipping: - Since the thickness is over 5cm, I would like you to cover the cost of Yu-Packet Plus (455 yen) if the item remains unopened. - If you are okay with opening and separating the items, please let me know in the comments. I will cover the shipping costs.
