Yoto card organizers, stands and holders
Three different problems: keeping the collection, showing the favourites, and finding one card in a stack. They are not substitutes for each other.

Sixty cards and a drawer that stopped working
Card Case
Yoto·Researched, not tested
Soft zip folder holding up to 64 cards in angled pockets sized for small hands. The unglamorous answer to a large collection, and the one that actually scales when a stand has run out of room.
The catch: Nothing is on display, so children browse by flipping rather than by looking — which undoes the reason the icons exist. Works best as the archive behind a small stand, not as the only storage.

Somewhere it lives, that looks like furniture
Wooden dock and card stand
Etsy maker — pine, food-safe oil finish·Etsy·Researched, not tested
Dock for the player with space for fifteen or more cards standing up and facing out, plus a groove at the front for the charging cable — the detail that stops a bedside table looking like a workbench. Can be engraved with a name.
The catch: Made to order, so not a next-day purchase, and fifteen cards is a display for the favourites rather than storage for the collection. A dock only helps if the player genuinely lives in one place.

Finding one specific card in a stack of sixty
Card tabs and ring set
Etsy maker — choose your own quantities·Etsy·Researched, not tested
Adhesive tabs with a punched hole, plus rings to thread them on. Cards hang in a bunch you can flip through like a keyring, and the tabs are thin enough that a tabbed card still goes into the slot. The cheapest fix on this page by some distance.
The catch: Adhesive on a card your child will handle daily, which is a one-way decision — peeling a tab off later can take the print with it. Amazon sells hundred-piece bundles cheaper, but you end up with far more than you need.
