I crocheted a small key holder with a lobster clasp using acrylic sock yarn. It could also be used as a small case. Please check the size in the photos. Please note that the color in the photos may differ from the actual product. This is a handmade item, so 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 flattened for shipping. Instant purchase is welcome.
