Thank you for viewing. One pair of Stample white crew socks, purchased in 2023, size 19-21cm: New, unused. One pair of Stample navy crew socks, purchased in 2023, size 19-21cm: Used once for a short time, washed. Two pairs of STREAM gray high socks, purchased in 2025, size 16-20cm: New, unused. One pair of MUJI's [Ankle-Shaped Right Angle Series] "Socks that Stretch Well All Over" 21-23cm: Tag removed, but new and unused. That's all. Except for the MUJI socks, these are probably perfect for a child around 20cm. The MUJI socks are also perfect for moms with small feet. I use a larger size and love the comfortable fit that doesn't feel tight. The two pairs of gray socks look slim, but I think they stretch quite a bit. My child has been repurchasing other colors of Stample socks, and they are a bit thicker, so they don't dig into the feet, and my child loved them.
