    You have chosen an AVIATOR metal, carbon fiber, or titanium credit card holder and are now wondering what the difference is between an acrylic and an aluminum inner frame. Or maybe you're wondering in general where the inner frame is located and what function it serves in your credit card holder?

    In this blog post, we will answer all questions about the inner frame and give you insights into the production of our Ultimate Slim Wallet.

    The Inner Frame: The Heart of the AVIATOR

    You may have already noticed that the AVIATOR is absolutely modular in construction, which means that you can take apart and replace all the parts yourself. The individual components are secured together with small Torx screws.

    The Inner Frame is the component between the outer plates, to which the front plate is screwed and the strap structures of the AVIATOR credit card holder are anchored with bolts. Essentially, the Inner Frame is the heart of the AVIATOR, holding all the components together.


    Acrylic or aluminum. Which is the right material for my card holder wallet? 

    You decide which material the inner frame of your unique credit card holder should have: acrylic or metal, aluminum? Both materials have arguments in their favor.

    Why should I choose an acrylic inner frame in my credit card wallet?

    • Robust

    Acrylic is a strong and durable material that is resistant to scratches and cracks. This makes it ideal for use in a credit card holder that is subjected to constant wear and tear. An acrylic inner frame reinforces the wallet and ensures that it maintains its shape even under heavy use.

    • Light
    If the weight of your credit card wallet is important to you because you take it with you when you exercise or want to minimize the weight you carry, an acrylic inner frame is the right choice. Acrylic is similar in weight to carbon and therefore does not add much weight.
    • Stylish

    In combination with the acrylic coin pocket, the acrylic inner frame completes the look of your credit card holder and gives it a modern and sporty appearance.

    • Inexpensive

    The acrylic inner frame is standard in your credit card wallet and is available at no extra cost compared to the aluminum inner frame.


    When is an aluminum inner frame only suitable for my credit card holder?

    • Strong and durable

    Aluminum is a lightweight but sturdy metal, making it the perfect material for a credit card holder that needs to withstand daily wear and tear. The inner frame provides additional support to the credit card case, so it does not wear out as quickly and maintains its shape and structure even with frequent use.

    • Easy to clean

    Aluminum is a smooth and non-porous material that is easy to clean and maintain. If your metal card case gets dirty, simply wipe it with a damp cloth to restore its shine.

    • Exclusive full metal

    Combined with the aluminum outer plates, the  aluminum coin holder and the aluminum inner frame, the AVIATOR credit card case becomes an exclusive full metal wallet. Its clear and modern appearance makes it the perfect partner for those who love clear and high-quality design.

    • RFID-protected

    The aluminum inner frame is RFID-protected, meaning that your credit card data cannot be read by electronic thieves. This additional security feature gives you peace of mind when you are out and about with your metal credit card case.

    • Combinable with colored titanium screws

    For a unique look for your credit card case, it is possible to combine the aluminum inner frame with colored titanium screws in  gold and  blue. This combination creates a wallet that is not only exclusive and stylish, but also durable and corrosion-resistant. The titanium screws are only compatible with the aluminum inner frame, they cannot be fully sunk into the acrylic inner frame.

Regardless of which inner frame you choose, when you invest in one of our credit card cases, you can be sure that you are getting a high-quality design product that has been made with care and will last a long time, possibly even forever.
