Hi, thank you for your interest again! But these are a pre-order and aside from the item price, I don't know how much P&P or fees are until they arrive to me end of May so I cannot give you a total invoice! I can combine them together with the straps, but P&P and fees won't be known until they have arrived to me and are ready to ship (so as the info says, payments will be done in two charges. First one for the item soon as possible and the second whenever they arrive to me)
But if you are still interested, it'll be 1000 yen via gift and 1100 yen via goods on paypal to trang-lu(@)hotmail(.)com !
