Open Box items consist of items that have been previously opened and may have either been unused or have very minimal use prior to being returned. These items are inspected to ensure they are in working condition and may undergo minor repairs. Newegg only guarantees your receipt of the Open Box product with the purchase of this item. Accessories and/or retail packaging MAY OR MAY NOT be included. Newegg will NOT send out any missing accessories, even if they are required to use all of the item's functions. Open Box items usually do not come with manufacturer or vendor warranty or technical support. However, warranty may be available if an item was never registered by a previous owner. Please contact the manufacturer directly to verify.
