The product is very nice and is in accordance to annoucement and what was expected for.
The only strong issue was the delivery system practice by the seller for oversea country shipment. It is crazy to put the shipment (4.200 yens)cost all together to the product price (4,100 yens)in the shipment invoice form (8,300 yens). The consequence for me was payment the importation taxes on 8,300yens and consequently the final price of this product became very, very, very expensive for me.
The seller site is very efficient for autometic purchase but does not have option to negotiate or change information for shipment procedure.
