Ergo ridged, heat treated, and web etched buttons

Hi, if you are looking for an awesome addition to your Ergo Alpha or Omega then take a look at these buttons because they are awesome! Ultraspinners offers 3 levels of heat treatment, ridged or smooth, and even a web etched version. I highly recommend these buttons! I'm a big fan of the Ergo lineup and if you are too then I highly recommend these heat treatment of the 3rd level, ridged, and web etched stainless steel buttons!
