All 4 of the chips, the one Whalen gave me and the 3 we bought xrayed so close that we thought all 4 had been repaired. Not likely in our opinions. The only answer was to peel the inlays and see what we were looking at.
Mine had been repaired, none of the other 3 were repaired. They were good chips, at least they were before we peeled the inlays. grin

The chips were made with a hollow resin reservoir under the inlays.
Mine had been drilled thru the resin reservoir. David had repaired it perfectly.
