Okamoto Socks Supplement Marude Kotatsu Socks I've been wearing these constantly for a year. There's quite a bit of pilling and fraying, so the condition isn't great. However, they still retain their heat-retention properties, so they're perfect for those who want to try the warmth of the expensive "Marude Kotatsu Socks" first! I'm looking for someone who understands that this is a junk item. I will compress and ship them in simple packaging. Due to my sick child's condition, the shipping time will be 4-7 days. If you have no questions, you can buy them immediately (^^) Thank you.
