Add extra panels to your Nanny Panel Playpen to create more space. The patented snap together panels make assembly super easy, super fast, and the most sturdy. No more panels falling apart from each other or that can't be assembled because they are too tight. Extendable by simply adding panels. Unlike others when in the 90 degree position, the Tikk Tokk Nanny Panel is not a limb entrapment hazard in the specified 30-50 (mm) range. It is taller and will therefore provide longer use. The high quality plastic construction is easy to clean and strong.
