Artline Jido Auto Mech Pencil 0.5mm

Terrible in more ways than one. Firstly, this is NOT an auto-advance pencil, even though it EXPLICITLY is advertised as one (even on the package!). Second, the pencil I received was completely sticky and gross all over because the rubber coating on the barrel had broken down in some way, probably just due to age. And lastly the back of the pencil just fell off as soon as I tried to use it. Honestly just buy any other mechanical pencil.
