Just to follow up from Michael's question on the last question, this is the entire RAWRtacular 'toolkit'!
On the base is an A3 water colour block weighted at 180g (woodfree for aome reason).
On top is my trusty metal rule (who's traveled the world with me), standard eraser, 0.5 mm HB (2) mechanical pencil, and last but not least a Faber Castell PITT inking pen (which is my poormans alternative to a Japanese 'Maru-pen')
