Princess Grace gave the twins each a Sunny Luce. These compact mirrors hold the powers of Prominence inside, and the Sunny Luce can be used to summon items that are from the Prominence, such as the Sunny Rod and the Crystal Fortulette. ("Luce" means "light" in Italian, emphasizing the shining nature of the power of the Prominence.)
Fine and Rein each have a Sunny Rod that can be summoned from their Sunny Luces. They are special wands that use the power of Prominence to bring forth good. The Sunny Rods can be summoned from the Sunny Luce at any time and do not require any of the twins to transform. They also have the ability to use the Sunny Rods on their own.
The Sunny Charge is a heart-shaped pillow that refills the Prominence back in the Sunny Luces. Since the Prominence has limited use, every night, Poomo recharges the Sunny Luces regain more power to use again.
Poomo first arrived to Fine and Rein in a special little box, but it's no ordinary box! Once inside, he can use Telepoomotion to teleport the box (and whoever grabs it) to any place on the Wonder Planet. It is also a resting place for Poomo.
Poomo routinely uses the Star Vial (Hoshi no Kobin) to check Fine and Rein's princess levels after every adventure. Because Princess Grace wanted Fine and Rein to become stronger so they can save the Wonder Planet, Fine, Rein, and Poomo would always go around the Wonder Planet to help others with the Prominence so their levels could be raised. The Star Vial checks are made to see if Fine and Rein have gained experience points, which is measured in a golden liquid. The liquid must completely fill the vial in order to reach the next princess level. If the girls pass, stars will fall in the vial and golden liquid would raise. If the girls do something wrong, the liquid inside will turn red and drain. If the girls neither gain nor lose points, nothing happens. The Star Vial later becomes the Crystal Fortulette after Fine and Rein reach the Fortune Princess level.
Given to them by their mother, Fine and Rein use the Decor Maker to make beautiful jewelry out of ordinary nuts and shells.
Inside the castle in the Meramera (Flame) Kingdom, the Bo Dragon Stone tells anyone how the Bo Dragon is feeling. Lione uses this magical stone to see how the Bo Dragon is doing.
It's not really a magical item, but Eclipse does so many tricks with his whip that it's almost magical. The whip can be extended with a button on the handle, and sometimes it's so fast that it practically cuts through anything solid. Eclipse can use his whip to swipe objects into his own reach, swipe objects out of other people's reach, remove obstacles, and deflect minor attacks (such as rocks thrown at him).
As a reward for saving Princess Milky, Moon Maria gave Fine and Rein the Feather Mewgram (Hane no Mewgram). With this item, Fine (or Rein) can make anyone dance by pointing it at them. In certain situations, it creates a diversion for Fine and Rein to escape or to help others calm down. The item has three separate dances: the Kurukuru Dance, the Ukiuki Dance, and the Fuwafuwa Dance.
After reaching the Fortune Princess level, Grace turned the Star Vial into the Crystal Fortulette. This fortune ball helps Fine and Rein transform into their Prominence forms and it can also be summoned outside of transformation to deliver a fortune that would later help them in the episode. Once summoned, the crystal inside the Fortulette spins and lands on a direction, number or kingdom crest. The Fortulette requires the power of the Prominence to use, as it is one of the items related to its power.
Just like Poomo, Boomo can use his box to teleport anyone to any place on the Wonder Planet with his dark magic. There is also a mirror in his box where he can keep watch on anything.
Roman has the power of the Prominence of his own, except the Black Luce is coated with a dark force.
Bright can use his boomerangs to swipe objects into his own reach, swipe objects out of other people's reach, and/or slice other impeding obstacles. On some occasions, his boomerangs managed to stop Eclipse. Later in the series, the power of the Black Prominence transfers itself into his boomerangs, allowing Bright to cast dark spells on anything.
The seven Grace Stones are Princess Grace's treasures that can grant immense power to whoever has the Prominence, but unfortunately, all seven must be used at once, otherwise the user can disappear forever. The Grace Stones are entrusted to the royal families of each respective kingdom to guard closely. Naginyo gives Fine and Rein a compact to store the Grace Stones in.
Sophie's treasure, a windmill music box, not only plays a cute tune when wound up, but it can control the winds in the Windmill Kingdom. Sophie received this when she was little from a Doggel, more specifically Doll's grandmother. The fanblades of the windmill also unlocks something more powerful...
