Great mechanical pencils in my preferred 0.7mm...stylish design and love the twist eraser

The sleek, minimalistic design certainly catches an eye

I kept buying new ones because of its sleek design--then one day I had seven, and I kept pulling out a new pencil from my pack and each one didn't work

Like, both 0.7 and 0.5 mm are the same exact designs, but the print disappears over time.2

either Diane's for its planned obsolescence or b) is a truly stupid product designed by stupid people.
