I crocheted acrylic yarn to make a key case. It comes with a carabiner, so you can attach it to your bag and carry it around. It has elastic and a key ring inside. I make them carefully, but please understand that there may be variations in the quality due to being handmade by an amateur. I make various other items as well.
