About this booster box

Mystery Booster - Booster Box Case [Convention Edition] (2021) is a sealed booster box from the Mystery Booster: Convention Edition Exclusives set. A sealed booster box contains a fixed number of booster packs from a single set — the classic way to open a set and chase its hits. Its current market value is $1,099.95, a premium sealed item.

What it's worth

It carries a market value of about $1,099.95 as of the latest update. The price has held fairly steady recently. Sealed products trade at a premium to loose packs because an unopened, untouched box is worth more to collectors and long-term holders.

Keep it sealed, or open it?

Whether to keep it sealed or crack it comes down to your goal:

  • Hold sealed — sealed Magic: The Gathering product tends to appreciate after a set goes out of print, since supply only shrinks.
  • Open it — if you're chasing specific singles, compare the box price to what those cards cost individually on the singles market.
  • Condition matters — factory shrink-wrap, no dents, and untampered seals all protect resale value.
  • Authenticity — buy from reputable sellers; weigh and inspect boxes to avoid resealed or weighed product.

Where to buy

You can grab one from the live eBay listings above, or support a local card shop that stocks sealed Magic: The Gathering product. Shops are also a good place to verify a box is genuine and in-hand before you buy.
