What is Original Packaging
These parts come in their original packaging, although they are currently open and may display an older date code. Each item is pre-owned but has been carefully maintained and is in excellent condition, ensuring reliable performance. Please note that Marci Network Hardware is not an authorized distributor for the manufacturers or tradenames listed, so the original manufacturer’s warranty does not apply. These parts are ideal for professionals or hobbyists seeking quality components at a great value.

What Is Marci Hardware Packaging?
Marci Hardware Packaging refers to items that are professionally inspected, tested, and securely repacked by Marci Network Hardware. These products may not include the original manufacturer’s packaging but are carefully packed to ensure safe storage and shipping. Each item is fully functional, well-protected, and ready for reliable use, offering excellent value without compromising performance.

What is Refurbished Packaging?
Refurbished packaging refers to the packaging used for a product that has been previously owned, returned, or repaired, and then restored to a like-new or fully functional condition. Unlike original packaging, which comes directly from the manufacturer, refurbished packaging may not look brand-new and could be a plain box or a repackaged version provided by the refurbished.
