I knitted hand warmers with 100% acrylic yarn. Please check the size in the photos. As these are handmade, please handle them with care. Please note that the color of the actual product may differ from the photos. As these are handmade by an amateur, there may be some imperfections such as uneven stitches and slight distortions. Please understand and accept this before purchasing. Please be aware that the item will be folded for packaging during shipping. Instant purchase is welcome.
