Your rep and justification for Vapman prices rest on your artisanal work and attention to detail. I suggest that you not rush like this in the future. Take your time and guarantee that each piece sold has the QC and polish that gives the user that "wow" reaction.So we produced practically day and night and probably due to the tiredness a mistake like this crept in.
Long nights and rushing is where errors and lack of attention to detail naturally creep in.
Folks can wait or you can wait until they are done instead of pre-sales.
