This listing is for two sets of G-TOUR2 strings, cut to the same 12.2m length as the packaged product. These are GOSEN products, so they are suitable for both hard and soft tennis, complying with the rules. They are also almost identical to the vertical strings of Xenoblizzard and Bulls Impact (both products use nylon for the horizontal strings). If you want polyester for the horizontal strings as well, purchasing this product is a much better value. Shipping will be via Yu-Packet Mini, with the strings in the condition shown in the second image. ・Search terms Gosen G-TOUR G-TOUR2 GTOUR g-tour gtour G-tour Polyester Poly Poly gut Soft tennis BULLSIMPACT Kaito Maruyama XENOBLIZARD Shunsuke Kamioka 12m
