Tiny - E - Bit Pencil by Maratac®

is compactor gives you the ability to write just about anywhere just like a regular pencil you can write just about anywhere comes with three heads which is really really good I kind of wish they had another case for it where you could hide the other two heads and then apply them as needed but still for the price range it's quite excellent

Writing isn't as dark as I'd like but it's a cool product and works

The size works in my hand, and it writes very smoothly.
