In reality, size doesn't hold much significance for a "Boundary Pearl" containing a vast life space. In the three-dimensional world, it appears spherical, but it takes other forms in different dimensions. When matched to an alchemical artifact disguised as a health bracelet, it shrinks to a diameter of less than 1cm, symmetrically paired with a Super Star Crystal of identical size, both transparent and clear, making it difficult for outsiders to discern the difference. Most would assume they're decorative, without realizing one is a special crystal storing Crystal Energy, and the other contains a vast life space.
Once the health bracelet alchemical artifact is on the left wrist and the Spiritual Imprint is recorded, it can no longer be removed unless the person passes away, allowing the dissipating Spiritual Imprint to be claimed by another.
