High socks for mountaineering, for children (women's available) 3 pairs set

These are the high socks for mountaineering that my children occasionally wore when they were in kindergarten or elementary school. I'm sure it was Montbell, but I'm not sure. I also used it in ski classes. The size is unknown, but it is about the same size as my feet at 23.5. There are pillings and other things, but I think you can still use it. Below is the name.

子供達が幼稚園〜小学生の頃に時々履いていた登山用ハイソックスです。確かモンベルだったと思いますが定かではありません。スキー教室でも使っていました。サイズは不明ですが23.5の私の足と同じくらいの大きさです。毛玉等ありますがまだまだお使いいただけると思います。下に記名があります。
