It is prohibited to modify any Apostrophic Laboratories font(s) for repackaging and/or re-release without an express written authorization by the designer(s) of the font(s) or Apostrophic Laboratories. Under no circumstance shall any Apostrophic Laboratories design or font design be sold or purchased. Email info@apostrophiclab.com if you want more information."
