Thank you for looking. These are socks from Silk Family. They are made of silk, which is very light and soft to the touch. Silk is said to improve skin beauty because its protein components are similar to those of the skin, and it also has the excellent property of blocking UV rays. Recommended for those who prefer natural materials and those with sensitive skin. 100% Silk Socks Length approx. 27.5cm, Width 7cm *Since there is no heel construction, they will fit if the length is suitable. I have listed the size as small, but I believe they would be fine for babies as well. Please refer to the size as a guide. No pets, no smokers. Also, please note that these items are also listed on other sites, and if they are sold, we will unfortunately have to remove them. We appreciate your understanding.
