Glitter Charms, known in Japan as Cure Decor (キュアデコル Kyua Dekoru), are special pieces that can be used either to revive Queen Euphoria or bring about the Worst Ending. Each Glitter Charm piece symbolizes the source of power of happiness of the Queen. The Glitter Charms are stored inside the Charm Chest.
Glitter Charm can be shaped like animals, food, fruit, flowers, cosmetics, and all kinds of other everyday objects, but they are all engraved with the Glitter Force logo. All Glitter Charm pieces have a small ribbon with a heart-shaped jewel attached.
When set into the Glitter Pact, each Glitter Charm piece will produce a specific item or grant the girls some power or ability. Most of these pieces were stolen by Nogo before the beginning of the story, when he attacked Jubiland and sealed its Queen. The stolen pieces were stored in Red Noses which the Shadow Realm villains use to create the Buffoon monsters.
Six special pieces, shaped like ribbons, are used by the girls to transform into Glitter Force.
Five special pieces, shaped like jewels, give the girl the ability to power-up to their next form, Tiara Mode, and to perform group purification attack Tiara Mode Torrent.
There is another power-up decor named Ultra, that appears in Episode 32 to grant Glitter Sunny a powered-up version of Sparkle Fire, doing the same for the other girls (with Glitter Lucky as last) in later episodes.
