Calligraphy marker and Rembrandt chalk pastels

A strange page of sketches of objects seen around me. The first 3 were drawn when I was at a primary school waiting for a class to start. The last 2 pictures were objects around my desk. I like how this was drawn carefree with an old calligraphy marker. I coloured these with an old vintage set of Rembrandt chalk pastels my Dad gave me.
