Features and Construction

Engineered for everyday reliability, this card box uses a simple but effective design that prioritises security and ease of use. The materials and dimensions work together to offer a slim yet functional storage solution.
Material and Build
The card box is constructed from nylon, a synthetic fabric known for its strength and lightweight feel. This material resists everyday wear and is easy to wipe clean, making it suitable for daily handling. The solid colour finish adds a uniform appearance without patterns or logos, keeping the design discreet.
Size and Practical Fit
At 90mm x 60mm x 14mm, the card box is small enough to slide into a front pocket or small compartment. The ultra-thin profile means it does not create a noticeable bulge, while the expansion slots accommodate multiple cards without stretching the material.
Uses and Placement

This card box adapts to various settings, from professional environments to casual outings. Its neutral styling and protective features make it a practical choice for anyone who carries cards regularly.
Event or Professional Use
For business meetings, conferences, or formal events, the sleek black card box keeps your ID, credit cards, and travel passes organised and protected from unauthorised scanning. The anti-theft function is particularly useful in crowded spaces where skimming devices may be present.
