About Mechanical Pig 01EDC & YEDC Collaboration: This is a mechanical slider jointly developed by 01EDC and YEDC. It underwent a 6 - month long test, achieving a perfect balance between the hand feel and the "ding - ding" sound. Separate Sale of Shell and Inner Core: There are 4 choices of shells; for the inner core, you can choose between the classic step - by - step feel and the dense step - by - step feel. Adjustable Stroke: There are two limit holes designed on the inner core, allowing you to adjust the length of the pushed - open stroke.
