I have checked their website and there is not one listed. I have emailed them several times with no response. I am trying to calm the confusion about their Qmonomer. For some reason my local beauty supply store is no longer carrying the Qmonomer but now only carries the HD monomer. Not only are they not carrying it, but they told us that the Qmonomer is discontinued and that HD has been its replacement. After further digging (on Nail Geek) I have come to the conclusion that Qmonomer is in fact not discontinued, but I have no idea how to contact them and find out what is going on and why I can no longer purchase it locally. Thanks for your help. :green:
