Rembrandt 2-Hour Whitening Kit

Rembrandt 2-Hour Whitening Kit is a tray-based teeth-whitening system introduced in 2004 by McNeil-PPC, a pharmaceutical subsidiary of Johnson & Johnson. Promotional material promises visible results after a single 2-hour session. The tray applicators are first molded and filled with a provided whitening gel, then placed in the user's mouth for 20 minutes. The process is repeated three times, with a 10-minute break between each wear.
