# The product object

> Sealed product — boxes, bundles, collections.

A product is something sealed: a booster box, an elite trainer box, a collection tin. Products
are priced like cards and tracked the same way, but they hold cards rather than being one.

Unlike every other id here, a product id is a **number**, not a string.

<ResponseField name="expansions" type="array">
  The expansions this product belongs to, as `{ id, name }`. Usually one entry, but not always
  — a Trainer Kit box ships two decks, and both are its expansions, so the field is an array
  rather than a single `expansion_id`. It can also be empty: such a product is still on
  [List products](/products/list), it just cannot be reached by `expansion_id`.
</ResponseField>
