Thank you for looking. These are arm covers from Silk Family. Both are very light and have a soft feel, made of silk. Silk is said to be good for beautiful skin 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. Silk Cotton 100% Silk Knit Arm Covers Length approx. 28.5 cm, Width 8 cm (flat measurements). I have listed the size as small, but I believe it would be fine for a baby as well. Please refer to the size for reference. No pets, no smokers. Also, as these are listed on other sites, we may have to remove them if they are sold. We appreciate your understanding.
