Kinstone Bag

The Kinstone Bag is an item received in The Minish Cap after completing the Deepwood Shrine and returning to Hyrule Town. It is a bag in which you keep all of your Kinstones. The Kinstones you find are only halves, so you must find people who have another matching half and fuse them in a process called Kinstone Fusion. As you collect more Kinstone pieces, the bag will grow and begin to bulge.
