This is a flat pack, L-shaped piece that folds into a self-closing, 3D pouch.
Tetrahedrons, four-faced pyramids, are used for a wide range of items from packaging (tetrapacks) to weapons (caltrops). This soft felt tetrahedron makes a good coin purse, or in a larger size with a strap attached, a clever shoulder bag.
