OHTO Mechanical Pencils SP-503P Editorial Review

The Auto Mechanical Pencil, Promecha 500P, Sharp for Drafting SP-509P is a half-priced model from Promecha, which is the little brother of the Ohto 1000 series. However, it has some quality and design issues that make it less favorable compared to other drafting pencils in the market. The cap is too small for the barrel, and it rattles Constantly, which can be unbearable and annoying while writing. The pencil is made of aluminum, but it doesn't justify the price as you might find far better plastic pencils that cost half as much. The product is not suitable for professional artists who demand quality and reliability. Therefore, if you are looking for a high-quality drafting pencil, this product may not be the perfect choice for you.
