Since 1961, Moon has been a leader in manufacturing decorative writing instruments, erasers, and school supplies for children and educators. Moon products are certified non-toxic. Moon is very proud that their pencils are made in the USA, featuring wood from sustained yield forests – the most environmentally friendly wood case pencils available.

As America's first triangular pencil, the Try-Rex is distinguished by an unusual shape – an equilateral triangle with rounded corners, which is uneasy to roll or fall while writing and nice for grapping. Jumbo size is nice for beginners.
