The finger splint is a medical tool designed to hold the finger in a certain position when it is hurt.My finger splint is based off the original. The main difference is the shape. Mine is round and it has to filled with a mold to stable it once the finger is inside. The outer part is just to protect the finger and that is why I don’t use just the mold. After your finger sits inside for about an hour and a half the mold should be hardened. Mine is more stable and it is completely closed.
