Investment Analysis: Why Unbroken Bonds Is a Smart Choice
Over the last five years, the Sun & Moon era has matured into a collector’s favourite, with sealed boxes becoming increasingly rare. Unbroken Bonds, in particular, has shown excellent performance as an investment due to several unique advantages:
1. Low Remaining Supply
Since Pokémon stopped printing Unbroken Bonds in 2020, sealed boxes have become scarce. Most remaining stock is held by private collectors or specialty retailers. As supply dwindles, market prices rise — especially for boxes verified as authentic and untempered.
2. Historical Importance of Tag Team Cards
The Tag Team GX mechanic marked a major milestone in Pokémon TCG evolution. These dual Pokémon cards introduced fresh gameplay dynamics and artistic collaborations. Investors often favour historically significant mechanics, and Tag Team cards perfectly fit that category.
3. Strong Resale and Grading Market
Unbroken Bonds has produced some of the most frequently graded cards of the Sun & Moon era. Collectors actively submit chase cards for PSA, CGC, and Beckett grading, contributing to consistent market liquidity. Even mid-tier pulls maintain strong demand due to stunning artwork and nostalgic value.
4. A Modern Classic Set
Unbroken Bonds sits at a sweet spot between affordability and prestige. It’s far enough removed from the modern Sword & Shield era to feel vintage but still recent enough to be accessible. As a result, European investors view it as a “modern classic” — a set with enduring appeal and high upside potential.
European Market Dynamics
Within Europe, demand for sealed Pokémon boxes has surged since 2021. The combination of post-pandemic nostalgia and growing investor interest has made EU-based retailers essential sources for authentic stock. Buying from TCGBoxShop.com ensures peace of mind and compliance with EU consumer protections.
- Authentic EU Sourcing – Every booster box is verified through official distributors.
- No Import Taxes – All shipments originate within the European Union.
- Fast, Insured Shipping – Secure delivery with full tracking.
- Secure Payments – Bank transfer and cryptocurrency options available via NowPayments.
In contrast to international auction sites or marketplaces, where fakes and resealed boxes are common, European collectors can rely on TCGBoxShop.com for verified authenticity and consistent quality.
Gameplay Value and Competitive Legacy
Unbroken Bonds wasn’t just a collector’s dream — it was a competitive powerhouse. Cards like Reshiram & Charizard GX and Dedenne GX became essential components in tournament-winning decks during the 2019–2020 season. Their synergy, versatility, and strategic depth influenced the meta for years.
Even though Tag Team cards have rotated out of standard format, they remain highly popular in Expanded and legacy play. Many European players continue to build Unbroken Bonds decks for nostalgic events or private competitions, keeping the set relevant long after its release.
How to Verify Authenticity
When investing in sealed products, authenticity is crucial. Counterfeit boxes can look convincing but usually fail upon close inspection. Here’s how to confirm that your Unbroken Bonds Booster Box is genuine:
- Check the wrapping: Pokémon logo patterns should be evenly spaced and printed diagonally across the shrink wrap.
- Inspect the weight: A sealed box should weigh around 450g.
- Verify the box edges: They should be factory-sealed without signs of tampering or glue residue.
- Buy from trusted retailers: Always source from verified EU shops like TCGBoxShop.com.
Storage and Long-Term Care
To protect your investment, store sealed boxes in a cool, dry place away from sunlight and humidity. For long-term collectors, acrylic cases are highly recommended. Maintaining box integrity is vital — a single tear in the wrap can significantly reduce collector value.
Market Trends and Future Outlook
From an investment perspective, Unbroken Bonds continues to perform well. In 2020, sealed boxes traded for under €250; by 2025, prices frequently exceed €700, with upward projections as supply tightens. Analysts expect stable annual growth rates between 8–12% as the Sun & Moon era gains “modern vintage” status.
Additionally, with the ongoing popularity of the Tag Team concept and the enduring appeal of Charizard-themed sets, Unbroken Bonds will likely remain a cornerstone of modern Pokémon collecting. As newer generations shift focus, older sealed boxes like this one will become even more coveted by both collectors and investors.
Expert Insights from Collectors
Veteran collectors describe Unbroken Bonds as “the perfect mix of nostalgia, playability, and art.” Influencers across Europe frequently highlight its importance in the Pokémon timeline. Many believe that, in the long run, Unbroken Bonds could become the “Evolutions” of the Sun & Moon era — a classic set remembered for its style and emotion.
Why Sealed Boxes Outperform Opened Packs
While opening packs offers excitement, sealed boxes preserve integrity and future value. Collectors view sealed products as time capsules of authenticity — untouched evidence of a specific Pokémon era. As the population of sealed Unbroken Bonds boxes continues to shrink, each remaining box becomes a rarer, more valuable asset.
