Collectible Items, also known as unobtainable items, are offsale items previously obtainable from gifts, events, and gamepasses. Collectible Items fall into 6 different categories: Strollers, Food, Vehicles, Toys, Gifts, and Stickers. The only way to acquire a collectible item is through trading.

Pets are not considered Collectible Items and instead are classified as Limited Pets.
