Using Sketchup Pro 2017:
To make the pen, Draw a circle then pull. On top of it draw a triangle then use follow me tool to create a cone as shown in the picture below.
Then draw a curve line and make a small circle on the tip of it then use the follow me tool. Scale it and connect it to the pen. Apply coloring materials.
And for the Diary, Draw a rectangle and pull. Then draw 2 lines on top and bottom of the three sides and make an arc on the remaining long side. Now pull the arc as shown in the picture.
Then pull the three sides inwards and draw lines as pages. Apply coloring materials and use Vray for rendering.
