Thank you for visiting! ( *´艸｀) These are very helpful when you're out and about with your baby, whether you're carrying them, using a baby carrier, or a stroller (*^^*) Perfect for taking your baby out on a cold day! These are all handmade. The fabric is fleece, and this is a set of three pairs: Nordic Red Pink Polka Dots Hearts Please note that we cannot exchange these for other types or colors <(_ _)> The inside is made of fleece fabric and is very warm, and they fit foot sizes up to about 12cm. Please be aware that these are not for outdoor use.
