A company that imports Sham Wow towel products to the United States is suing Venable for alleged malpractice, accusing attorneys of giving bad advice on customs matters and a government investigation—forcing the company to hire other lawyers to clean up the mess.

Square One Entertainment Inc., whose chief executive officer Vince Offer was the public face of Sham Wow, says it faced a U.S. customs penalty of more than $700,000 due to the firm’s negligence. The company reached a $50,000 agreement only after bringing in other lawyers, it said.
