Translation Results Requested Through Conyac Made Public

I bought 3 pkgs of Olfa blades to use for gifts. One pkg was given to a friend and she complained that each blade she could only get 5 cuts and then the blade would not cut thru her fabric and she would have to use scissors to separate the threads. She has used a number of the blades and each performing the same. I would like to return 2 unopened pkgs for a refund as I do not want to give these as gifts and have the same performance. I think it would also be fair to have the other opened packaged replaced. Thank you
