I'm selling these on consignment because the owner, who purchased them, recently retired and no longer needs them. These are unopened and being sold on consignment. There are two pairs, gray in color. For those who understand that these have been stored at home. I will also be listing other men's socks, so please feel free to combine them if you'd like. I have a young child, so I've set the shipping time to 4-7 days just in case. I usually ship within 1-3 days, but please confirm beforehand if you need it urgently. There are no smokers or pets. I will generally ship using the most affordable method (including regular mail). Please contact me if you prefer anonymous shipping. If the shipping costs more than expected, I will add the difference. When using Mercari shipping, I may change between Rakuraku and Yu-Yu shipping depending on the size of the package. Thank you.
