We have catalogued 4 Ilia Topuria White Sparkle cards, Panini's unnumbered short print, in Prizm and Donruss Optic from 2022 and 2023. 4 have a photo of the actual copy.
White Sparkle is the white-glitter parallel Panini keeps for its own channels: it does not come from a hobby or retail box. It began as a Panini Rewards exclusive and in 2017 moved to its own three-card packs sold through Panini Instant, per Panini's announcement.
Unnumbered. The card carries no serial. Its rarity is known from what Panini once said and from how rarely it appears.
The /20 is a borrowed figure. Panini stated in 2017 that each Prizm Football White Sparkle was “limited to 20 copies or less”. It said so about that product; for UFC it never published anything, and sellers apply the figure out of habit.
The autographs are numbered. In Optic UFC the White Sparkle autographs are 1/1; the base cards are not.
How it reached Ilia Topuria's cards
For 2022, Panini announced that the Prizm UFC and Donruss Optic UFC White Sparkle packs were distributed through the Instant Access Club, its paid membership programme, per the club announcement. The packs were later resold loose, but that is the origin.
Prizm UFC 2022 #115: the White Sparkle of his first card. The official hobby and FOTL sell sheet does not list it, because it was never in those boxes.
Donruss Optic UFC 2022: both the Rated Rookie #110 and the Dominators #17 insert have a White Sparkle; the checklist lists them among the unnumbered parallels, as this listing shows.
Prizm UFC 2023 #167: the same mechanism a year later.
How to recognise it
The background is a white prizm with glittering particles, not the plain Silver or the lined Hyper.
Cards on this list are marked SSP: short print, no number. If a listing says “/20”, that is a convention, not printed data.
How to read this list
They are rookie-year parallels, not the rookie itself: the difference is explained on the Ilia Topuria rookie cards page.
