100g Sanwa Spring
bag (10x) of 100g springs from the official Sanwa store in Japan. Engineered to work with any Sanwa button listed on the website. Highly recommended for Pop'n Music players, and players of any other game who enjoy a heavier feeling!
I'm an old fashioned IIDX player that prefers playing on a 100/100 setup. I recently ordered sets of 100g springs and switches for my setup, and I'm thrilled to say not only did I receive everything as described, but the ordering process and shipping were fantastic. Highly recommend!
