摘要 |
A retractable writing surface system including a binding mechanism and a pocket directly bound to the binding mechanism, the pocket having an inner cavity. The system further includes a polymer writing surface at least partially received in the pocket. The writing surface is movable between an extended position wherein at least part of the writing surface is exposed for writing upon by a writing instrument, and a retracted position wherein less of the writing surface is exposed for writing upon by the writing instrument compared to when the writing surface is in the extended position. At least part of the writing surface is located in the cavity when the writing surface is in the retracted position.
