hexagonal pen stand (A)

-double wall hexagonal pen stand with imprinted month calendar on each six sides for July until December. And we could slide another hexagonal (but just 1mm bigger) over the pen holder onto which comes the calendar for the months January until June. After June one could easily slide the outer layer off and the last 6 months of the year will appear. For 2010 our customer could decide to create two new layers (each layer 6 months of 2010) to slide over the pen holder so at least this pen holder could be reused.
-Material: papercard or PP or plastic or PVC (since we could also do the inner part in such material and then use two hexagonal papercard (printed) layers. After one year (removal of two layers) the ‘skelet’ in plastic or PVC or any other material will stay (this skelet can be neutrally white or even already printed with our customers logo in black and yellow for permanent advertising goals every after.
