SATINIOR12 Pairs Women Toe Topper Socks Toe Liner Half Seamless Socks No Show Low Cut Socks for Women Girls

Country of manufacturing?

What kind of material? Are they nylon?

Do these satinior half socks come in size large?

I am a Diabetic and my toes get so cold but I can't stand a full sock I wear a size 12 woman's shoe would these fit and the binding not be too tight?
