Important are a clear product description, the condition of the packaging, the language of the edition, and the exact specification of which contents are guaranteed to be included. Especially with an upcoming set, buyers should be cautious of exaggerated promises regarding value, rarity, or pull rates. A description is reliable when it distinguishes between confirmed product contents and random booster contents. For collectors, it also matters whether the Collection Box is original, unopened, and suitable for their own collection.
