100 Nintendo chips for sale in the original box. MD-22 per Roger Eisenstadt (RIP). Last pic is only an example of a milled chip. All chips you will recieve will be unplayed (by me) and in original condition.
$100 shipped CONUS Paypal F&F. Thanks for looking!
Not much is known about the composition of the material used. Some say they are plastic injection molded and others will say compression molded. I found no injection dimples present anywhere on the chips. If you do a quick search, there are a few old threads discussing them...like this one. Maybe a chibes exbert will chime in with some insight.
