Venus Jumbo Pencils

Primer Print 1

The Primer Print 1 is a red jumbo pencil with a 10 mm diameter (a bit larger than the blue Primer Print 2 below). This version of the pencil has a big spot for students to write their name on. Bob Truby's site has photos two different versions of this pencil. 

Primer Print 2

I found this collection of Primer Print 2 pencils at a second hand store in July 2018. They're in really nice condition. They're a large diameter (approx. 8 mm) round pencil for younger students.
