Up for sale here is this set of 5 brand new pushbutton covers. These are beautiful brushed-aluminum knob covers and looks amazing. They will fit any pushbutton with a 3mm square shaft. They will work great for the pushbuttons on the Realistic STA-200. These are a tiny bit thinner than the originals, and do not have the exact same beveled edge as the old ones, and are a bit shinier, but they're almost exactly the same size and is a good replacement. If you want yours to match, why not replace all of them? These measure 10.4 mm in diameter and 16 mm long.

US shipping and handling is $5, and international is $18, no matter what quantity you buy. All my small parts are set up for combined shipping, so just use the "add to cart" feature and then check out all at once, and it will combine shipping. If you have any questions, please ask.
