Perforations: Good perf means almost equal perfs on both sides and if there is no trace of a perf I describe it as trimmed straight. Just OK means that in my opinion there are sufficient perforations, do ask for a scan if it is important to you. Hopefully any other descriptions are clear as being between these descriptions.
