The E string is ball-end. Size is for 4/4 violin. The price is already at its limit, so I cannot offer a discount. This is a Pirastro violin string set, Violino. It's a new GDAE set. These strings are from the same series as Pirastro's Obligato, Evah Pirazzi, and Evah Pirazzi Gold, but have the lowest tension and the warmest tone. It's often said that Obligato sounds similar to gut strings, but Violino sounds even closer to gut strings. The tone is so wonderful, it's a shame that it's not well-known in Japan. Please give it a try. Violino Violino
