The opening mechanism goes by pulling the cover downwards and vice versa in the closing sequence. The Ultra Capsules can be stored by sliding them downwards into the slot provided.
- Despite being able to hold only 4 Capsules, Riku/Geed is still able to change to either of his forms, which would require at least 9 slots and still have enough space to store empty Capsules, and the other Capsules he has collected.
- An Ultra Capsule Collection Box was produced by Bandai China. It can hold up to 24 Capsules.
