The Blood Type A+ Positive Tactical Molle Buckle is a functional and durable accessory, crafted using 3D printing technology with high-quality PLA plastic. Designed to clearly display your blood type in emergencies or during outdoor activities, this buckle is compatible with 1-inch Molle webbing systems, making it ideal for backpacks, tactical vests, belts, and other gear. This handmade accessory is perfect for pairing with your tactical morale patches or adding to your patch collection. As a 3D printed product, it may have subtle layer lines or minor variations in color/texture, which are natural and do not impact performance. Avoid exposing the buckle to temperatures above 60°C (140°F) and handle with care to prevent damage.
