Observing a passenger give up a pocketknife before boarding a plane in Charlotte led Heather Lowry to form a company to deal with such occurrences. Lowry and her business partner Sherry Anderson pooled $10,000 in savings to form CheckPoint Mailers, Inc. A Greenville family later invested $100,000. CheckPoint Mailers will ship carry-on-contraband in bomb-resistant boxes at any of twenty-eight U.S. airports wherever the mailer wants. The company has eight full-time employees and twenty-eight contractors. Currently the business is generating about $80,000 a month in sales.
