Seimitsu LB-30 Solid Color Balltop (30mm in Diameter)

These are 30mm balltops, 5mm smaller in diameter to the 35mm standard that you see on most joysticks today.  Using this smaller ball top gives you a sense of a stiffer joystick feel.  The thread of this balltop is the same as the 35mm standard and will fit all joysticks from Sanwa Denshi, Hori and Seimitsu.
