I had purchased some of those " Peaceful " tabs about February last year [ if my memory serves ] , however , before I got around to trying them the vendor contacted me advising of a mistake - apparently some blank sheets had gotten mixed up with those already dipped ... [ an understandable error considering the nature of the work being performed ].
They replaced what I had bought , and threw in extras as well .
consumer : I am certain that your tabs will be really good like these type always are , [ and not some of the few erroneous blanks that got mixed up with the others ]
EDIT : now that I think of it in hindsight , I had contacted the vendor for info about storage - he asked what tabs I had bought [ the lay date ] and then advised me of the problem ...
