■ Why Security Features Matter for TCG Display Cases
As the global market for trading cards continues to expand,
stores are increasingly required to enhance security measures, especially when displaying high-value singles and graded cards such as PSA items.
In this edition of “What Makes Our Showcases Exceptional,”
we focus on two of the most important security features:
Polycarbonate Doors and Dial-Type Slide Locks.
① Polycarbonate Doors – A Material Strong Enough for Bullet-Resistant Applications

● Superior Impact Resistance Compared to Glass
Polycarbonate (commonly called “PC”) is known for its incredible strength.
This material prevents:
- Breakage from impact
- Forced entry attempts with tools
- Damage from accidental drops or collisions
It dramatically enhances the safety of high-value card displays.
● 99.9% UV Protection to Prevent Card Fading
One of the standout features of polycarbonate is its
astonishing 99.9% UV-blocking capability.
This offers exceptional protection against fading caused by ultraviolet light,
ensuring your cards maintain their vibrant colors even after long-term display.
● Additional Advantages
- Highly resistant to chemicals
- Excellent flame-retardant properties
- Lightweight and easy to handle compared to glass
- Maintains clarity over time
Polycarbonate offers the ideal balance of
security, preservation, and usability for store environments.

② Dial-Type Slide Locks – Strengthening Security with an Additional Layer

● Add-on Lock for a Dual-Layer Security System
While our showcases come equipped with standard locks,
installing an additional dial-type slide lock provides even stronger protection.
Freely set any 3-digit combination
No tools required for installation
Prevents forced opening from the outside
No physical key management needed
A simple yet highly effective way to upgrade your showcase security.
● Benefits of Using a Slide Lock
- Affordable and easy to adopt
- No risk of losing keys
- Quick to operate during busy store hours
- Reinforces existing security with minimal effort
Perfect for stores wanting stronger protection without major modifications.
■ Conclusion: Protect Your Valuable Cards with Reliable Security
The combination of Polycarbonate Doors × Dial-Type Slide Locks
is one of the most effective ways to enhance the security of your TCG showcases.
