This item was included with a purchase in March of this year. The fabric is durable, so you can put Pilates goods like massage balls inside the socks. I am listing it for sale because I don't plan to use it, and I'm organizing my belongings. It is new and unused, but it has been stored in its original product box since purchase, so there are fold marks as shown in the photos, and there is no special plastic wrapping. I touched it for the first time to take the photos. I would appreciate it if those who understand this would consider purchasing it.
