Check the listing for details. Mandolin Strings by Black Diamond, Martin, Adamas & GHS - Read description. Condition: Used. Listed at 15.00 USD. Mandolin Strings by Black Diamond, Martin, Adamas & GHS. The green and black pack that is pictured is NOT included because I realized it was an empty pack after I took the picture. I ONLY SHIP TO THE Continental USA and I DO NOT SHIP TO PO BOXES! *Please note-the shipping price is a flat rate. I mostly ship fed ex but may use USPS or UPS if need be (depends on where you live and the cost). DO not even ask for a reduced shipping rate. Ebay takes a percentage of the shipping cost in fees, plus I not only pay for shipping but all the supplies it takes to ship your item. I start my items low and CAN NOT absorb any extra costs. SHIPPING IS AS STATED in the listing!!!*I pack items very well and everything has a tracking number. Once I mail an item I can't be held responsible for what happens to the package. If it gets lost, damaged or stolen then I will do all I can to get the claim filed, etc....however I can't control what happens after I mail it. With this said I will work with the buyer to help in any way I can. *I will only ship to the address you have on file with eBay so it's up to you to make sure the address is current and correct. *Buyer to pay for return shipping if an item is returned.
